Mode: force_next
Version: 54.0.2837.0
Reproduction Steps: 
1. Navigate to docs.google.com and create a new document.
2. Make sure that CVox Next is enabled.
3. Type the line "I lkie the Google!!!!!"
4. Tools>>spellcheck...
Expected: the misspelled word is announced, and a correction is suggested and vocalized... at the very least, the misspelled word is vocalized.
Actual: Lots of babble that culminates in the misspelled word being announced... sometimes... if a user listens that far. A user can navigate the window with CVox review commands, however if a user moves too far in a direction, they are brought out of spellcheck and back to the document... potentially causing confusion to the user.
