` key gets stuck after window loses and regains focus

[kazukazu123123]

When the reims-vgpu window becomes inactive and then active again, the ` key sometimes behaves as if it is being held down.

Pressing any key once (for example, A or B) seems to release the stuck key.

Steps to reproduce

1. Open the reims-vgpu window.
2. Switch to another window so that the reims-vgpu window becomes inactive.
3. Switch back to the reims-vgpu window.
4. The ` key behaves as if it is being held down.
5. Press any key once, and the issue stops.

Expected behavior

No keys should remain in a held state after the window loses and regains focus.
