Bug that is supposed to be addressed keeps bugging me

I know the release notes say that this bug has been fixed:

  • Fixed bug whereby some misspellings were not being underlined.
    Unfortunately this bug is alive and kicking in Spanish (I’m not sure if this remains a problem with other languages, as I have been working on a translation since upgrading to 3.3.1 a couple of weeks ago, but I can say that in Spanish it is most definitely an issue)
