### Godot version

v4.0.beta15.mono.official [4fa6edc88]

### System information

### Issue description

The entire window loses focus if you ungrab focus from a Control. 
This doesn't seem to happen in Beta 14 and older betas.

### Steps to reproduce

1. Create a Control that can grab focus (tested with LineEdit and TextEdit)
2. Grab focus
3. Release focus via release_focus() or hiding the node
