It's not possible to rename any node while using wayland session under my linux distro. Using Godot 4 beta15. Tried changing keyboard layout and same result. If I swith to X11 session then it works. Also beta14 doesn't have this problem with wayland session.

### Steps to reproduce

Literally try to rename any node under wayland session with beta15
