Currently, whenever there is a rendering problem with a math tag big red color is displayed.
I propose to change that and display the input LaTeX code instead with the error message in a footnote or a popup.
Moreover, a tracking category should be assigned to that particular page.
However, to start with the implementation I need to find out.
- How to assign tracking categories?
- How to bring the message into the footnote, i.e. are there build in MediaWiki functions I could use, or do I need to use plain HTML?
