Thank you for your work on this.

Sorry, the fixes are not helpful at all. HTML elements should never be translated. Stop creating such patches or MRs. Think first.

I am removing the issue tags wrongly used. I apologize for bumping this issue.

Since the options are just listing HTML tag names, it is not necessary to translate them.
Without any context, then, translators would not understand if they need to leave those strings as they are or translate them. It would be fun to see acca1 because an Italian translator translated h1.
