Indeed. How strange. I have had the same browser for years, but had to update, and this seems to be part of the update. Dumb. It even underlines terms that are typical of source codes like “alignnone”. Voilà: here it is underlined. And beside it “voilà”, also underlined.
Well, so be it.
Thanks for your answer.
Right now I don’t think it is worth looking deeper into it, as it will bug more people and there there will be a remedy of some sort.
When I press Update – I always get a message that the “Proofreader” has suggestions for my post. The spell check is OK, but I do not like the proofreader’s attempts to change what I have written. How can I disable this ?
