[HELP] Mac makes key remain pressed after screen capture on webgl

[hwk9120]

Hi, I have a keyboard system that if some keys were pressed some key objects change their color.

However, I have a problem on macOS.
After screen capture using the shortcut (cmd + shift + 4 or 5), the shift key remains pressed state.
When I used Input.GetKey() in Update() function, it was called on every update eventhough screencapture was finished at all and unity application was focused.

[Process]

1. press shift + (nothing or some keys like ‘a’) + cmd + 5
2. Activate screen capture
3. press esc to escape screen capture
4. check console log → shift + (nothing or some keys) are pressed
5. press shift again
6. check log → keydown event doesn’t work but keyup event works

Can I force to release that pressed key?
