Loss of bookmarks possible when switching groups

[skomorokh]

I was considering not reporting this until I had time to troubleshoot it further, but it happened again so I wanted to at least create a placeholder so others are aware of the risk (though the extension is marked experimental so I suppose this is implied).

When switching groups I have encountered a situation where the group you switched away from could somehow have its contents replaced with a copy of the group you switched to. Seems more likely when you haven't let the tabs fully load. Some kind of timing issue with all the async stuff going on? It somehow starts synchronising the new set of bookmarks before the destination folder changes?

Hopefully I can find time to dig into this a bit more and come up with a way to reliably recreate it, but this might be enough to go on?
