The event we are stopping for is the stop to single step over a breakpoint. We should have decided not to broadcast that to the public event queue, since it's an implementation stop of the "continue". It almost looks like the stop hook is getting triggered by a not-broadcast event, though that doesn't make sense.
I'll have to look at this more closely, I'm in the middle of something else right now. Thanks for adding the Unsupported...
