Some extensions (e.g. mw:extension:Cite) establish tags (<ref> in this case) which are parsed on a "one-off" assumption. I.e. structures like Primary text<ref>Outer footnote<ref>Inner footnote</ref> continuation of outer footnote</ref> continuation of primary text simply will not currently parse, resulting in the dreaded and rather unfriendly
Cite error: Closing </ref> missing for <ref> tag

error. Surely it is past time to address such a fundamental issue?
