Thread:Extension talk:SectionHide/Some odd formatting in MediaWiki 1.22/reply (3)

And now that's broken the nesting, i.e. H2 divs get closed before the H3 divs they contain are opened, so collapsing the H2 div only collapses the text up until the H3 header... So I'm guessing the  is important somehow but I really cannot live with all that white space. I'll keep tinkering with it...
