  - Fix broken reference list numbering in Firefox

    Same as Ib6e9de6.

    We must reset the build-in "list-item" counter to make this code behave
    sane in Firefox. It looks like this is even described in the CSS spec
    and it is not Firefox having a bug, but Chrome being "clever" and not
    following the spec.
