MathJax converts a cite error to a formula

After I added a reference using VisuaEditor[1] I noticed there was no <references /> tag in the page, and consequently there was the usual cite error which says "Cite error: There are <ref> tags on this page, but the references will not show without a {{reflist}} template (see the help page)."

The problem is: this message was displayed as if it were a formula, when I was using MathJax.

The message is normal if I'm logged out (since the default is PNG images instead of MathJax)
