###!!! ASSERTION: Creating accessible for node with no document: 'content->GetDocument()', file nsAccessibilityService.cpp, line 1379

we'll get the assertion when the sequence of action is fulfilled:
1) add text nodes to text accessible
2) remove text accessible

the reason, we try to fire text events for the node that isn't in document already.

Probably we should have more strong rules in nsAccEvent::ApplyEventRules and exclude un actual events.

fixed testcase but issue is still valid for www.webmd.com where tabs are changed dynamically. There I get many 'create' events and preceding them reorder event.

I'm getting a LOT of these warnings on www.spike.com. In fact the debug trunk build is unusable... and the warnings never end. Tested with NVDA 2009.1.

The example is not valid anymore since Gecko architecture was changed: we process element insertion after timeout. I don't see this assertion in mochitest long, also I don't see it when I run spike.com with NVDA. Closing as worksforme.
