Templates feature, new guided tours, and lots more!
What you were trying to do is an expected use case, I just didn't think about trying it myself as I was developing the feature. This happens quite frequently and it is hard to avoid it.
It is the main reason why we have frequent beta releases and why we waited for a new beta cycle before showing this feature. By the time we make a new stable release, all of these small issues will be sorted. As for the people that are interested in trying out the beta releases, the fix will be available soon, so it's ok to just forget about it.
