NVDA doesn't announce spelling error for words when reading line in LibreOffice Writer

Originally reported on the LibreOffice a11y mailing list: https://listarchives.libreoffice.org/global/accessibility/msg01055.html

Corresponding bug report for LibreOffice: https://bugs.documentfoundation.org/show_bug.cgi?id=157696

Steps to reproduce:

1. make sure to have a dictionary installed in LibreOffice, like https://extensions.libreoffice.org/en/extensions/show/english-dictionaries
2. start NVDA screen reader
3. start Writer
4. type "Hello world, wrrong spelling." for first paragraph
5. double-check that "wrrong" is visually marked as having a spelling error (red underline)
6. hit Enter to create a second paragraph
7. press Up key to move to the first paragraph again

Actual behavior:

NVDA announces the text of the first paragraph without indicating that there is a spelling error in the word "wrrong", just says: "Hello world, wrrong spelling."

Expected behavior:

NVDA should indicate that there is a spelling error in the word "wrrong", as it does when taking the above steps in MS Word instead:
"Hello world, spelling error wrrong spelling."

This needs work in both, LibreOffice and NVDA. I'm planning to submit a PR.
