SwAccessibleParagraph::GetWordBoundary is called when you navigate
word by word normally done by pressing Ctrl+Right/Left arrow. This works
well as long as the word is an actual word. Problem is that what we
land on is not always an actual word the cursor will for example stop
at . (periods) and at the moment that won't be exposed to accessibility
tools such as NVDA screen reader. Orca on Linux seem to have some type
of workaround but it dosen't really work. I'll try to find out if the
workaround is actually in Orca or in the way LibreOffice exposes things
to atk.
