All the latest failures on this issue show that the failure happens due to an early abort of WebDriver:ElementClick due to the actor being destroyed before the actual click event has been received by Marionette. Means the top-level browsing context that will be removed by the click is still present:

Probably the race here comes from the fact that the iframe is removed before the parent frame, and as such we can still switch to it once the button is gone. Maybe we should run some script evaluation to fetch an element from the parent frame and wait until it returns the no such window error?

This actually wont work as well if the currently selected browsing context is gone because we won't be able to send a command anymore. I'm actually not sure how we can solve this problem at all for WebDriver classic. By using a BiDi script execution call we could find out when the parent is closed, but it's not available here.

As such I feel that we may have to mark this test as intermittent failing especially for slow running builds which include debug, ccov, asan, and tsan. I'll attach a patch to get the manifest file updated.

Hello Henrik! Could you please take a look at this? It looks like it still failing with that failure line.

Thank you!

Hello Henrik! Could you please take a look at this? It looks like it still failing with that failure line.

Looks like it's indeed failing for opt builds but so far it seems to be way less frequent. I would suggest that we keep an eye on it over the next days / weeks and make a decision later on if we also want to mark opt builds as pass and fail. As best we should have used a separate bug for the patches already landed.

Should we consider removing this test if we assert a behavior which is racy? A test should reliably pass regardless of the performance of the platform.

Given that this test cannot be run with classic on it's own we discussed with Chrome folks and will make a special test that uses both classic and BiDi. As such we need to move it to a new folder under webdriver/tests/.
