Plugins on FL Studio (Windows) cannot shrink if smaller than a certain size

[danferns]

I found that on FL Studio I can only make the GUI larger if it is smaller than 531x375, beyond which I can make it larger and smaller. [...]

Resized: WindowSize { physical: PhysicalSize { width: 531, height: 375 }, logical: LogicalSize { width: 531.0, height: 375.0 }, scale_factor: 1.0 }

This also happens with the egui_gain example for nice-plug.

EDIT: Only happens when resizing by dragging the window frame. egui_gain resizes perfectly fine if I drag the resize handle instead.
