Created attachment 311891 [details] test/repro I wrote a test in r217587 that is broken because the async task's completion block is called synchronously, and UIScriptController is just not designed to deal with that. I've attached a patch that adds a test that reproduces this, but don't really have a great plan to fix (I'm just going to paper over it in my test for now).
