The regression range is: https://hg.mozilla.org/mozilla-central/rev/2494fafdeae721029ce499c9367f522c76aaa9c1 The cause is that, before the front and actor would be destroyed together. With the change to getFront, the destruction of the actor happened well after the front. I added a fix but there is a problem -- we might actually test this somewhere, but the test passes. I am not sure what is different in our test environment and when testing manually, but the test included in the first patch here is exactly the steps that i used to reproduce this. It might take some investigation into why the tests behave differently. We might have some cleanup for convenience.
