[1.5.4] Selection Group not functioning proper in Segementation window

[micheus]

Everything works fine until we get to step 4. As expected you would assume any changes to the group in the segment window would apply normally. Sadly such is not the case. Any and all changes made to any selection groups, creating of new selection groups will register in the window. but once you leave segmenting mode they're entirely forgotten or not respected at all.

AutoUV Segmenting is an intermediary window for temporary selection of where the cut will be done.
You must have noticed it doesn't happen when you are in the next window - AutoUV Editor - maybe because in this case the selections can be reused at any time.

I'm not sure we can say it's a bug.
