What Changed

This supersedes #5169 and includes its Projects Search close-transition fix.

  • Keep dialog payload and form state mounted while open changes to false.
  • Clear retained state from onOpenChangeComplete(false), after Base UI finishes its ending styles.
  • Keep the Projects Search mode in place during close, then reset to command mode on the next regular open.
  • Move the expanded image viewer onto Base UI's dialog lifecycle so opening and closing use the same transition model.

Why

Several dialogs used payload presence as both their data and their open state. Closing cleared the payload or reset the form immediately, so the popup disappeared before Base UI could render its ending styles. Opening animated, but closing vanished in one frame.

The dialog's visibility and payload lifetime are now separate. Closing changes visibility first. Payload and form cleanup happen only after the close transition completes.

Note

Low Risk
UI-only dialog lifecycle changes; no auth, data, or backend behavior is modified. Close-timing bugs are the main residual risk.

Overview
Fixes close animations by splitting visibility from payload lifetime. Dialogs now set open: false first and only clear form/payload state in onOpenChangeComplete(false) after Base UI ending styles finish.

This pattern is applied across chat, git, settings, command palette, SSH password, WSL/Tailscale, and the right-panel sheet. The expanded image viewer is moved onto Base UI Dialog so it uses the same open/close transitions, keyed by a generation counter on reopen.

Note

Preserve dialog state through close transitions across web UI components

  • Dialogs now retain their internal state until onOpenChangeComplete fires (after the close animation finishes), rather than clearing state immediately on onOpenChange(false). This prevents visual content flicker during exit transitions.
  • Affected components include commit, pull request, SSH password prompt, image preview, WSL/Tailscale confirmation, add-provider-instance, and pairing dialogs.
  • The ExpandedImageDialog is refactored to use @base-ui/react/dialog primitives and is now fully controlled via open/onOpenChange/onOpenChangeComplete props; a monotonically increasing generation key forces remount when reopening the same image.
  • RightPanelSheet removes keepMounted and is always rendered when its trigger conditions are met, with visibility controlled by the open prop.
  • Behavioral Change: several dialogs now hold their data objects (e.g. pendingDefaultBranchAction, pendingTailscaleServeSetup) until close fully completes rather than nulling them immediately on close.

📝 Walkthrough

Walkthrough

The changes update dialog state handling across chat, command palette, SSH, and settings components. Several dialogs now retain content or state until their close transition completes. Command palette content mounts when activated and unmounts after closing. Sheet launcher shortcuts can be disabled while the panel is closed.

Command palette content mounts when the palette or an associated intent opens. It unmounts after the close transition completes.

The SSH password prompt uses controlled open state and removes its request after closing completes. The input is set as the dialog’s initial focus target.

Publish, provider, pairing, WSL, and Tailscale dialog state is reset or cleared after close completion. The provider dialog remains rendered while closed.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Bug fix

Merge Risk: 🟡 Moderate · up to c776f

Prevent SSH prompt dismissal while a password response is pending before merging; otherwise a failed submission can leave users without the error or retry form. The publish wizard also still changes content during closing.

Security Architecture Review

Security architecture risk: 🔵 Low · up to c776f

A pending SSH password response can outlive its dialog, removing the user's error-recovery path. The impact is bounded by request-specific resolution and backend cleanup. No broader increase in access or authority was established in the inspected workflows.

Retained concerns

  • Medium · reliability · inferred: Closing the SSH prompt during an in-flight password response releases its UI ownership independently of the response outcome. The cancellation response is suppressed by the concurrent-response guard, while close completion removes the request. A subsequent submission failure therefore loses its visible error and retry path. This is an introduced authentication-recovery regression, not an established authorization bypass.
Security review details

Security Blast Radius

  • inferred — The demonstrated recovery failure affects the active SSH authentication prompt in the local desktop renderer. Request-specific queue removal and backend resolution constrain it; the inspected path does not establish credential delivery to a different request or environment.

Trust Boundaries and Controls

  • observed — SSH password resolution continues through the schema-validated desktop IPC method carrying requestId and password. The backend removes the matching pending entry, rejects absent requests, and distinguishes cancellation from password delivery.

Resilience and Maintainability Implications

  • observed — Backend password waiting has a timeout and requestId-based cleanup. This provides containment if the renderer loses its recovery UI, but does not restore that UI or make dialog closure equivalent to successful cancellation.

One finding on the dialog-transition migration: the SSH password prompt's mount-time focus no longer runs now that open starts false. Everything else (Base UI onOpenChangeComplete for deferred reset/unmount, the ExpandedImageDialog port to Dialog.Root, and the RightPanelSheet open-prop change) preserves the existing geometry, class ownership, and close semantics.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This is a broad production UI lifecycle change spanning many dialogs, panels, focus handlers, and asynchronous workflows, with behavior changing during close transitions rather than in one isolated component. Unresolved findings describe possible state loss, keyboard interference, blank dialogs, and modal-dismissal failures, requiring human validation.

One finding on the lightbox migration to Base UI Dialog — the rest of the dialog lifecycle plumbing (state kept alive until onOpenChangeComplete, resets moved to close-complete, sheet now animating instead of being conditionally unmounted) looks consistent with the shared dialog contract.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Keep the prompt open while a response is pending.

Base UI allows Escape to request dismissal. (base-ui.com) If the user presses Escape while respond(password) is pending, cancelPrompt now closes the dialog before respond(null) checks isRespondingRef. That guard skips cancellation, but close completion still removes the request. If the password response fails, the error and retry form are no longer visible.

Check isRespondingRef.current before closing in cancelPrompt, so dismissal follows the same pending-state restriction as the buttons.

Proposed fix
   const cancelPrompt = () => {
+    if (isRespondingRef.current) {
+      return;

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Remove the immediate reset from handleOpenChange.

handleOpenChange still calls resetState() when closing starts (Lines 585–587). Closing from the repository or summary step therefore switches the wizard to the provider step during the close transition. The new completion handler repeats the reset but does not preserve the closing content.

Keep only props.onOpenChange(open) in handleOpenChange. Reset state in onOpenChangeComplete(false).
