In excel, a certain document causes freezes #6216

I will send the document to @michaelDCurran Privately.

1. Open the excel document.
2. Navigate down to row 9. Other rows in the 40's freeze NVDA as well.
3. Expected behavior: Contents are read.
   Behavior: NVDA freezes.
   This is being sent privately because I don't want the document in the public since I didn't create it, and can't figure out how to reproduce.
