Seems like this happens when I exit via [x] as well, but not from the File menu, it doesn't seem to do anything (i.e. no crashes or weird behavior), invalid? or maybe wontfix?

no, these are bugs. the problem is that you have to figure out which JS object isn't listening to enough handlers or, if it seems to be listening to all reasonable handlers, having found the object, determine why the handlers it would listen to aren't being called.

sadly, while it's easy to find who is calling (stack trace), finding out who is being called is painful (i have code in my tree which doesn't work). the easiest thing to do is to log all add's and remove's and then when you get a call check the caller's list of adds+removes and see who hasn't been removed yet.
