Regression from #72277 (most likely, I didn't test)

### Steps to reproduce

1. Add some Node to your scene
2. Add a TileMap as a child
3. Select TileMap
4. Fold its parent in the scene tree
5. Restart the editor
6. The TileMap selection is restored and so is the folded node, resulting in a weird paradox

### Minimal reproduction project

		String path = shader->get_path();
		String text = path.get_file();
		if (text.is_empty()) {
			
			text = TTR("[unsaved]");
		} else if (shader->is_built_in()) {
			const String &shader_name = shader->get_name();
			if (!shader_name.is_empty()) {
				text = vformat("%s (%s)", shader_name, text.get_slice("::", 0));
			}
		}
		bool unsaved = false;
		if (edited_shader.shader_editor) {
			unsaved = edited_shader.shader_editor->is_unsaved();
		}
		
		if (unsaved) {
			text += "(*)";
