Here the failure details:

Note that WebDriver:ExecuteScript triggers a navigation and directly returns. Each following command can run into the AbortError situation and as such would have to be changed to retry calling the actor method for the new actor pair. For some methods we may can't do that, eg. execute_script maybe.

[Julian Descottes [:jdescottes]]

I expect to handle a few of those in Bug 1662808, blocking this bug on it.

Comment 6

[Henrik Skupin [:whimboo][⌚️UTC+1]]

Please note that most of the discussion on this bug actually belongs to bug 1671347, which is about handling the AbortError by using a proxy. As such I requested to get the patch moved over to the other bug.

Here we should really only discuss the closing of a frame or window.
