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

N/A
for (int i = 0; i < animation->get_item_count(); i++) {
		String anim_name = animation->get_item_text(i);
		if (animation->is_item_disabled(i) || animation->is_item_separator(i)) {
			continue;
		}
		Ref<Texture2D> icon;
		if (anim_name == player->get_autoplay()) {
			if (anim_name == SceneStringNames::get_singleton()->RESET) {
				icon = autoplay_reset_icon;
			} else {
				icon = autoplay_icon;
			}
		} else if (anim_name == SceneStringNames::get_singleton()->RESET) {
			icon = reset_icon;
		}
		animation->set_item_icon(i, icon);
