Thread:Project:Support desk/How to disable wikisyntax-based parsing of CSS/JS pages?/reply (2)

If you install the Extension:SyntaxHighlight GeSHi extension... — already done, but I want to see geshi-highlighted syntax not only on saved page, but on preview as well. Strange, but preview of userJS subpages works more smartly than preview of critical system messages in MW namespace. And also it's strange to see some things like Category:$1 in Special:WantedCategories and User:Cool Javascripter (whose name is credited in JS pages) in Special:MostLinkedPages. That why I'm here. But thank you for your response anyway.
