### Godot version

### System information

Win10

### Issue description

In the Godot 4.1. Beta3 Scene Panel, node names are overlapping the icons to the right. Like visibility icons, script icons ...
Especially apparent with longer node names:

This is _not_ an issue in Godot 4.0.3:

### Steps to reproduce

Give long node names and resize the Scene Panel
