It seems that this started from Bug 1597877 after it was merged to central.
Maja can you please take a look?

The above log excerpt isn't useful at all. So here the correct one:

This seems to happen on Windows only.

There is also a different failure in the same test that might be related, and caused by the failure above:

Comment 8

[Henrik Skupin [:whimboo][⌚️UTC+2]]

As of right now there are no more failures since Dec 14th. Maybe the fix on bug 1603266 helped here and we do not have any dangling events hanging around anymore?

Maja, can you please check? Thanks

Comment 9

[Maja Frydrychowicz :impossibus (was :maja_zf) (needinfo me)]

This might be due to Page.navigate returning too early (Bug 1603776). In the flaky test, we make a call to Page.createIsolatedWorld (see testWorldc below) right after Page.navigate. The isolated execution context is created for the previous URL even though we should have finished navigating by then.

This test happens to catch the problem because we get an extra executionContextDestroyed event as a result.

status-firefox73: affected → disabled

Ryan, why did you set the status to disabled for 73? Nothing has been disabled on that branch:
