#Steps to reproduce this bug

1. open either txt file
2. using ctrl f to search for something that exist more than one time in a document
3. press enter to exit search window and move the first match
4. if I press F3 now, nvda will speak no more search result in this direction, but not speak the match search result, but actually the focus has moved to the next match

#basic info
