STR (with the NVDA screen reader):
- Enable CTW.
- Load this page: https://docs.microsoft.com/en-us/dotnet/standard/async-in-depth
- Actual: Crash!
- Expected: No crash.
There seems to be a text leaf with no text attributes. Perhaps NVDA poked the tree before the cache message arrived? I'm not really sure why this happens. In any case, it doesn't hurt to null check attributes.

:dmeehan, this code is behind a pref which will still be disabled by default in 99. Do you still think this needs to be tracked for 99?

Thanks :jamie for the info - I will remove tracking for 99.
