It does appear that a didChange went to the server before the didOpen. I'm pretty sure this is going to be related to delayOpenNotifications, though scanning through the code I don't see an obvious problem.

I'll do some more digging later this week. If you do find a way to repro, please let me know. If we can't find anything, then I may revert that flag (I'm starting to wonder if it's worth the effort!).

Disabled delayOpenNotifications until we know whether it's the cause of

I'm disabling delayOpenNotifications for now until we've tracked this down. It could be unrelated, but I suspect it's related and I haven't been able to repro yet.
