Hello! In Studio 2020.10.4 I have experiences several bugs when using vertical tab groups. (The function which opens two .xaml docs side by side).
Say I have two documents open: A.xaml and B.xaml. Sometimes, when I want to insert (for example) an empty seqence to document B, it gets quite funky:
Instead of doing something with document B (which I have clearly selected), Studio deletes everything (!!) in document A and replaces this with the empty sequence.
When I close one of the documents it works properly again.
I fear that this is the reason for another bug I have quite often experienced: where the collection of arguments is not the same as the list of arguments (the list which you can see in an invoke workflow).
So: there are definetly some weird bugs with vertical tab groups. Something gets wrong, sometimes, when saving the document(s).
