Windows desktop app completely losing keyboard focus

RemarkIt commented 1 month ago

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.

create a new project, e.g. flutter create test_app --platforms windows
add a new TextField widget
build and run
press Win+D to minimize all apps
press Win + D to regain focus
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)
