Subject: Fix paragraph highlighting for mouseover on edit buttons

Dokuwiki does not generate section edit buttons for h4 sections. Therefor, the
edit button next to a h4 section belongs to a previous higher-level section.
The AJAX-y paragraph highlighting onmouseover the edit button does not highlight
all sections up to to higher-level section which owns the edit button, but only
the last, i. e. h4 section.
This patch highlights all sections up to the heading the edit button refers to.
