Little edge selection bug after an undo.

 From:  NightCabbage
Hmm also...

Say you have 2 objects.

You hide one.
Then you move the other.
Then you go undo, to undo the move.
Now the second object is unhidden (in a buggy way that sometimes doesn't update until you try to move something).

I'm not sure how to reproduce it though... probably not much help in that case...
