Sorry, but I don't quite understand how waiting for gvtBuildCompleted
fixes the problem with the BridgeContext.
I should have said gvtBuildStarted (although completed would work it's
later than it needs to be). The problem is that the BridgeContext
isn't disposed of (which completes the disentanglement) until shorty
_after_ all the UpdateManagerStopped events are delivered. So what I
am suggesting is waiting for the first event after UpdateManagerStopped so
you know that the Canvas has disposed of the BridgeContext for the previous
document.
I will probably fix this problem with BridgeContext disposal shortly
(over the weekend) so you could just wait for that (I think
UpdateManagerStopped should signal that the Canvas is done with the document).
