Issue: Windows desktop app completely losing keyboard focus
Labels: a: text input,platform-windows,a: desktop,has reproducible steps,P2,fyi-text-input,found in release: 3.22,found in release: 3.23,team-windows,triaged-windows

### Steps to reproduce

Rarely it happens with windows desktop app, that the application completely stops being responsive to any hardware keyboard input. I managed to discover only one scenario where the issue can be reliably reproduced.

1. create a new project, e.g. flutter create test_app --platforms windows
2. add a new TextField widget
3. build and run
4. press Win+D to minimize all apps
5. press Win + D to regain focus
6. try writting into the TextField

### Expected results

Input appears in the TextField

### Actual results

No input appears. Also the windows alert beeping sound is triggered. Note, that the app is not responsive to the keyboard at all (e.g. Tab behavior)
