@Texou do you still have this issue with last NVDA version and last libre office version? Which braille display are you using?

It seems we unfortunately do not have any response from the author since 5 years. I tend to close this issue. But before doing that, maybe someone with a braille display could test quickly.

@david-acm, @zstanecic, @ruifontes, @nvdaes, @lukaszgo1 could someone please test if this is still an issue in Libre Office?

I can't reproduce this. However, after inserting a formula and going to the pane with functions with f6, this list of functions in a category is not readable. It is just reported as a "scroll pane". However, since the categories read corectly and the scroll pane is not accessible at all (either in speech or braille) this is clearly a separate issue.

Thanks for reporting back. I am closint this as works for me. Please comment on it if you still see this issue.
@bramd would you mind to open a new issue for that scroll pannel? Thanks.
