When dragging edges with no items selected (good!):
The grouped item edges stay together.
When dragging edges with items selected (bad!):
The select item edge moves by itself on a second drag As far as I'm concerned the second should act like the first. The only thing I've done is group the items beforehand using the built-in REAPER function.
Hmm can't reproduce. Can you provide a sample project? Also what version is this?
v6.58. I'll zip a project and send over email.
EDIT: I believe I've found the issue. This only happens when the crossfade editor dialog is open. I think I've even narrowed it down to only happening when the edit grouped items is ticked:
So still a bug but I'm hoping you can recreate it now (I've sent over a very small project zip in any case).
