For tools this is not an issue as it’s not an issue because it’s temporary. It’s understandable why it exists as a temporary thing so it’s not an issue on it’s own.
There is one issue though. If another tool is being loaded, but the add to startergear popup has not appeared.
Then if you insert another tool, and the second tools popup tries to appear when the first tools popup has not been closed a roact error happens which breaks the Toolbox UI (making it un-navigatable) and the temporary model stays.
This has likely been fixed but I’m not sure.
