Estimated code review effort: 5 (Critical) | ~90 minutes Merge Risk: 🟡 Moderate · up to The PR can place forced side callouts partly off-screen and may focus a hidden element, making content unreachable or focus behavior ineffective in affected cases. Merge should wait for these bounded correctness fixes or explicit owner acceptance; the remaining lint and demo issues are minor follow-up. Sequence Diagram(s)sequenceDiagram

732-745: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low valueConsider observing the fire-and-forget task in
OnSetIsOpen.
OnSetIsOpenstartsToggleCalloutFromOutsidewith_ = .... That path awaits consumer callbacks (OnToggle,OnOpen,OnDismiss). An exception thrown by a consumer callback is then unobserved, so the failure is silent. A small continuation that reports the exception through the renderer keeps the diagnostics.♻️ Proposed change

In `@src/BlazorUI/Bit.BlazorUI/Scripts/general.ts`:
- Around line 41-47: The noDismiss branch in the window scroll handler calls
Callouts.reposition synchronously for every event, causing repeated layout
measurements. Update this path to use the existing throttle or
requestAnimationFrame batching mechanism, while preserving the early return and
ensuring reposition runs at most once per batch.
In
`@src/BlazorUI/Demo/Client/Bit.BlazorUI.Demo.Client.Core/Pages/Components/Surfaces/Callout/BitCalloutDemo.razor`:
- Around line 670-679: Replace the plain-text Anchor content in BitCallout at
src/BlazorUI/Demo/Client/Bit.BlazorUI.Demo.Client.Core/Pages/Components/Surfaces/Callout/BitCalloutDemo.razor
lines 670-679 with a focusable BitButton, then update the displayed Razor source
snippet at
src/BlazorUI/Demo/Client/Bit.BlazorUI.Demo.Client.Core/Pages/Components/Surfaces/Callout/BitCalloutDemo.razor.cs
lines 1023-1032 to match the accessible demo.
In
`@src/BlazorUI/Tests/Bit.BlazorUI.Tests/Components/Surfaces/Callout/BitCalloutTests.cs`:
- Around line 994-1008: Update BitCalloutShouldRespectVisibility so the
BitVisibility.Visible case explicitly asserts that the rendered style contains
neither visibility:hidden nor display:none, while preserving the existing
positive assertions for Hidden and Collapsed.

83-97: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winAlign
focusablewith the filter the focus trap uses.The comment on lines 75-76 states that this uses the same set the focus trap cycles through.
wrapFocus(line 455) filters candidates withoffsetWidth > 0 || offsetHeight > 0 || getClientRects().length > 0.focusableaccepts any element whoseoffsetParentis not null.
offsetParentis not null for avisibility: hiddenelement that is not fixed positioned.focusFirstElementcan therefore pick an element that cannot take the focus, and.focus()then leaves the focus on the trigger. The two filters can also disagree on which element is first, so the element focused on open is not always the one Shift+Tab wraps back to.Use one shared predicate for both paths.
♻️ Proposed shared predicate
- const focusable = (el: HTMLElement) => { - if (el.offsetParent !== null) return true; - - const style = getComputedStyle(el); - return style.position === 'fixed' - && style.visibility !== 'hidden' - && el.getClientRects().length > 0; - }; + const focusable = (el: HTMLElement) => Utils.isFocusable(el);Add the predicate next to
_focusablesand use it inwrapFocusas well:// A hidden element is not a place the focus can land. offsetParent is null for a display:none // subtree, and also for a fixed-positioned element that is perfectly visible, so a box is // measured instead and visibility is checked by hand. public static isFocusable(el: HTMLElement): boolean { const style = getComputedStyle(el); if (style.visibility === 'hidden') return false; return el.offsetWidth > 0 || el.offsetHeight > 0 || el.getClientRects().length > 0; }🤖 Prompt for AI Agents

In `@src/BlazorUI/Bit.BlazorUI/Components/Surfaces/Callout/BitCallout.scss`:
- Around line 35-40: Add a blank line before each affected double-slash comment
in BitCallout.scss: the nested-overlay comment at lines 35-40,
responsive-transform comment at lines 69-71, sizing comment at lines 78-82,
height-cap comment at lines 133-141, and arrow-size comment at lines 190-193,
resolving the scss/double-slash-comment-empty-line-before violations.
- Line 2: Update the SCSS import in BitCallout styles to omit the .scss partial
extension while preserving the existing media-queries.scss import path.
In `@src/BlazorUI/Bit.BlazorUI/Scripts/Callouts.ts`:
- Around line 487-502: Update placeOnPreferredSide and its caller position to
accept visibleLeft and visibleRight, then clamp the computed horizontal left
position in the forced left/right placement branch to the visible horizontal
bounds, matching the existing automatic four-way placement behavior. Preserve
the current vertical clamping and side-placement calculations.
In
`@src/BlazorUI/Demo/Client/Bit.BlazorUI.Demo.Client.Core/Pages/Components/Surfaces/Callout/BitCalloutDemo.razor`:
- Around line 133-142: Update the DefaultIsOpen value in the BitCallout demo to
true so the callout initially renders open and demonstrates the parameter’s
effect; mirror the same value in the corresponding displayed snippet in
BitCalloutDemo.
