In bug 1353922, I accidentally wrote a patch that put merged multiple tabs into one zone (specifically tabs from the same TabGroup). There shouldn't be anything wrong with doing this. However, it caused a couple crashes in the GC (all in devtools):

I think it might be a good idea to investigate these. Perhaps the same thing could happen without my patch.

Actually, I don't think this is related to zones. It seems more likely to be caused by the use of zone groups.
