There is no getter for a group so I think ignoring the error is the only solution.

I assume mypy is complaining here. Would it help to make the list explicit? fortexfontin ["cal","rm","tt","it","bf","sf","bfit"]: Copy link ContributorAuthor ZPyrolinkSep 9, 2025 Choose a reason for hiding this comment The reason will be displayed to describe this comment to others.Learn more. Unfortunately mypy consider`textfont` as a`str` and the sum also as str so we have the same error timhoffm reacted with confused emoji Copy link Member timhoffmSep 9, 2025 Choose a reason for hiding this comment The reason will be displayed to describe this comment to others.Learn more. Ok in that case, ignoring is likely the simplest solution.
