bug#68827: 29.1; Latex mode: tex-verbatim face has priority on font-lock-comment-face

[Gabriele Nicolardi]

    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:

I have attached a figure to better illustrate the issue.

I also opened an issue on StackExchange: https://emacs.stackexchange.com/q/80201/15606
