[New-bugs-announce] [issue46181] Destroying an expaned Combobox prevents Entry focus until Alt+Tab

[Jonathan Lahav]

New submission from Jonathan Lahav <j.lahav at gmail.com>:

Happens on Windows.

Observation:
When an expanded Combobox is destroyerd, widgets in the window can't get focus until Alt+Tab forth and back.
Buttons can still be clicked, but focus can't be obtained by widgets, entries fro example, not by clicking nor by the Tab or arrow keys.

The attached file contains a minimal reproduction example.

Motivation:
I develop the GUI for a complex application at work which needs to recreate its GUI layout upon a combobox selection, thus destroying the combobox as well.
