That's done now and announcement of spelling errors when NVDA announces 
a line in Writer works with the LibreOffice changes from the 
above-mentioned Bugzilla ticket and the corresponding NVDA change ( 
https://github.com/nvaccess/nvda/pull/15649 ) in place, i.e. it will 
work with the upcoming versions LibreOffice 24.2 and NVDA 2024.1.

The fact that LibreOffice was switched from custom attributes to 
attributes according to the IAccessible2 specification also implies that 
assistive technology that was previously only supporting the custom 
attributes has to be adapted to accept the IAccessible2 text attributes now.

For NVDA, this has been implemented in the pull request mentioned above. 
If you rely on the feature of announcing formatting information, I'd 
recommend to update NDVA to 2024.1 next year before updating to 
LibreOffice 2024.2. (Announcement for text formatting will not work with 
NVDA 2023.x and LibreOffice 2024.2 and above).

In a quick test with JAWS, it didn't announce any text attributes when 
pressing Keypad_Insert+F, neither with nor without the recent 
LibreOffice changes in place, so it seems like that's not implemented 
there at all. (I can't take any closer look because that's a closed 
source product.)

If anybody wants to test the current development versions, I'm happy 
about feedback.

If anybody is aware of other assistive technology that should be taken 
into account, I'm thankful if you either notify the developers yourself 
or let me know so I can take care of this.

Regards,
Michael
