Current Behavior

When you close the popup, there's a gray semi-transparent overlay that remains on the screen until you switch to a new tab/page.

Expected Behavior

Page should reset to its normal background after closing the popup.

Steps To Reproduce

1. Run app from reproduction project.
2. Press the "open popup" button.
3. Type something into the Entry in the popup.
4. Press "close popup".
5. There should be an overlay still stuck on the page.

Environment

- .NET MAUI CommunityToolkit: 9.0.0
- OS: Windows 10 Build 10.0.19045
- .NET MAUI: 8.0.21

Anything else?

Only happens when you type something into the Entry (if the Entry was pre-populated with text and you erase some of it, the bug doesn't happen).

Only happens in a TabbedPage (setting the app's MainPage to a normal content page doesn't cause the same issue).

Only tested in Android, not sure what happens with other platforms.

should the issue be visible in your video? it isn't - or I'm being completely blind to it.

When debugging, pressing the Tab key on the hardware keyboard displays an overlay, but this overlay is not an overlay added on the Popup side.

The steps to reproduce are as follows.

1. Start the app.
2. Press the Tab key on the hardware keyboard.
3. Press the "Open popup" button.
4. Type something into the Entry in the popup.
5. Press the "Close popup" button.

An overlay will appear in step 2.
The overlay that appears when you press the Tab key does not cover the entire screen, so the title bar is not covered.
The overlay added by Popup is different from this overlay and covers the entire screen.

[Popup]

If my guess is correct, this overlay should disappear if you press the Tab key again.
Therefore, I don't think it's a bug.

Yep, Tab fixes it. I guess it's just a problem with the emulator? Thanks for the help anyways.
