Exception for selection movement

Saw this when joining a collaborative session. The old window that I was typing 
in ended up orphaned and unable to push mutations to the edit session.

I also see  this exception in and around my Out Of Memory exceptions.  I'm not 
sure if they're linked or not, but this exception could be preventing channels 
from closing, thus gobbling up memory.
