### Godot version

Latest 4.0.dev (a3a42159e31db27f8ae7c1ecad6a9ed417cb05de)

### System information

Ubuntu 22.04.1 LTS

### Issue description

Ctrl+Shift+F (Find in Files) in the text editor, for example, causes my laptop to freeze consistently. I also reproduced it with F1 and Ctrl+Shift+R, as well as by using the dropdown instead of shortcuts.

### Steps to reproduce

Trivial

### Minimal reproduction project
