I'm not sure what to make of this.

It looks like the file just didn't load. But the test file is very simple. I suspect this is not editor-related but some kind of intermittent failure in page loading itself.

The warning "An event was posted to a thread that will never run it (rejected)" looks interesting. It means an event was posted to a thread that has already ended its event loop as part of Shutdown. Of course we have no idea what thread or event that might be, but if we did then maybe we could solve this.

Hmm, that line about leaking a timer was interesting.  By some code inspection, it seems like the timer thread has fired a timer event to a thread which is shutting down.  I don't know if that is something which is expected...

Not sure about "expected", but it could easily happen, no?  As long as the thread that's shutting down didn't cancel the timer and all.

Mass marking whiteboard:[orange] bugs WFM (to clean up TBPL bug suggestions) that:
* Haven't changed in > 6months
* Whose whiteboard contains none of the strings: {disabled,marked,random,fuzzy,todo,fails,failing,annotated,leave open,time-bomb}
* Passed a (quick) manual inspection of bug summary/whiteboard to ensure they weren't a false positive.

I've also gone through and searched for cases where the whiteboard wasn't labelled correctly after test disabling, by using attachment description & basic comment searches. However if the test for which this bug was about has in fact been disabled/annotated/..., please accept my apologies & reopen/mark the whiteboard appropriately so this doesn't get re-closed in the future (and please ping me via IRC or email so I can try to tweak the saved searches to avoid more edge cases).
