### Issue description

[simplescreenrecorder-2023-08-30_15.01.51.webm](https://github.com/godotengine/godot-proposals/assets/71937306/537d92b9-4f98-4fe6-adf4-71297be0471a)

### Steps to reproduce

press space

### Minimal reproduction project

void EditorLayoutsDialog::_deselect_layout_names() {
	
	layout_names->deselect_all();
