Zimit2: HTML demos on developer.mozilla.org (MDN) pages are not working

[benoit74]

See https://dev.library.kiwix.org/content/developer.mozilla.org_en_all_2024-05/interactive-examples.mdn.mozilla.net/pages/tabbed/section.html for isolated test case.

This worked well in zimit1 and is working well in replayweb.page

mod = if_ and url with mp_ seems pretty special
