Steps to reproduce:

1. start NVDA
2. start MS Word
3. type
4. Type "hello world"
5. move text cursor to the beginning of the text
6. press Ctrl+B (in English UI) to enable bold formatting (for newly typed text)

Actual behavior:

NVDA announces "Bold off", even though bold is now enabled for newly typed text, as the button in the toolbar/ribbon shows.

Interestingly, the Speech Viewer output seems to first have the correct, then the incorrect state (and maybe only the last one is announced?):

ctrl+b
Bold on
Bold Off

Expected behavior:

NVDA should announce "Bold on".
