Noticing this for the first time tonight in Chrome. It's related to us using MessageChannel to send things over to the iframe and back, and I guess blocking on it returning? We should see if we can deal with any of it.

Hey, Id like to give fixing this a try.

@edyedy123 this is not going to be an easy bug to fix, FYI. You are welcome to try it, but I really have no idea how to get you started on it. If you still want this, let me know; but you might also have an easier time with something else. Let me know.

Ok, I'Il try somthing else.
