The Parser handles internally <math> if $wgUseTeX. However, if $wgUseTeX isn't set, the user should be able to provide the math tag functionality using an alternative extension. Currently, the parser gets confused at extensionSubstitution() seeing a math and trying to handle it when it's not supposed to.
Created attachment 6697 [details] Skip <math> if not enabled
