Has been triaged, issue is waiting for implementation.
Steps to reproduce:
Actual behavior:
I also saw this behavior sometimes in edit fields in Chrome or Firefox, but not as obvious as in Outlook.
At some point NVDA is totally silent, epsecially when using focus mode. In browse mode, it seems at least speech is not cancelled, but the performance while selecting is really bad.
Following shows that there is at least a one seccond freeze regularly while selecting content:
This occurs both with UIA for MS Word in Outlook on or off.
I added advanced logging for events, speech manager, synth driver, UIA and speech, and following is written to the log:
So it seems NVDA is not able to establish an NVDA Object on IA2 caret movement when selecting text.
Expected behavior:
NVDA should speak selection while selecting text, and no freeze should occur.
