Editor replaces wikitext of broken math with the texvc error message

[Niels]

In mediawiki, texvc validates latex notation before passing it to XeTeX for rendering.

Without FCKeditor, texvc validates and, if the tex is invalid, it inserts an error message in the output. If you edit, you get your original almost-right tex back in the wikitext, and you can easily fix the tex error.

With FCKeditor, the editor apparently parses the error output into new wikitext, so if you commit a tex syntax or lexing error, you have to edit --> wikitext --> clean out all the error text and markup --> add math tags --> fix the tex error.

I wonder if this is related two these two localhost image bugs: #2624 #3269

FCKeditor was retired and is no longer supported. All active development was moved to its successor, ​CKEditor 3.x, that is a fully mature and far superior product. We recommend you upgrade as soon as possible.
