Hi, I switched to Emacs 29.1 recently. I noticed that the tex-verbatim face used in latex-mode to highlight the \href argument has priority on font-lock-comment-face. The tex-verbatim face is defined in tex-mode.el: (defface tex-verbatim '((t :inherit fixed-pitch-serif)) "Face used to highlight TeX verbatim environments." :group 'tex) I think that this is a bug or, at least, very annoying. This is a fragment of LaTeX code that contains the issue: ibitem{Zhang:1992fs} % %X.-m.
