[Windows] Space is no longer entered after opening and dismissing the system menu with Alt+Space #189495
Description
Steps to reproduce
- Run a Flutter Windows desktop app with a standard text input widget such as
TextField. - Focus the text field.
- Switch to the Korean IME.
- Type Korean text normally.
- Press
Alt+Spaceto open the Windows system menu. - Press
Escto dismiss the system menu. - Try pressing the spacebar.
- Switch to English input and press the spacebar again.
Expected results
Pressing the spacebar should continue to insert a normal space character after the system menu is dismissed.
This should work regardless of whether the current input mode is Korean or English.
Actual results
After opening the Windows system menu with Alt+Space and dismissing it with Esc, pressing the spacebar no longer inserts a space into the Flutter text field.
Once this happens, the problem is not limited to Korean input. Space input also does not work after switching back to English input.
