Steps to reproduce:

With braille display connected:

1. Go to advanced NVDA settings and enable use UI automation for MS Word.
2. Open Word 365.
3. Type text. Notice that the text I'm entering is not showing up on the braille display until I press right arrow.

Actual behavior:

When I type text in Word 365 with a braille display connected and UI automation enabled, the text I've entered is not showing up on the braille display until I press right arrow. When I disable UI automation support, the issue goes away but everything becomes more sluggish.

Expected behavior:

When typing text in Word 365, the words I'm typing should be coming up on the braille display. I should not have to press right arrow just to see what I've typed on the braille display.
