Make all textarea fields foldable

[framay <franz.mayer@…>]

Make all textarea fields, such as Description and custom textarea fields foldable / expandable.

I just saw on ​demo-0.12 that this feature has not been implemented in Trac core yet.

Maybe I can provide a patch for this feature, currently it looks pretty bad, when I add CSS class foldable to h3 or div, like this:

    <h3 class="foldable" id="comment:description">
      Description
      <a href="${href.ticket(ticket.id, action='diff', version=description_change.cnum)}"
         py:if="description_change" class="lastmod trac-diff" title="$description_change.date">
        <i18n:msg params="author">(last modified by ${authorinfo(description_change.author)})</i18n:msg>
      </a>
    </h3>

The foldable arrow is placed after label "Description" … Why that?

See #10381 for a possible patch for foldable custom textarea fields. But still header "Description" is not foldable.

All the tickets for {20} from last year have probably been seen multiple times by now, yet are still to be triaged…

Since #10381 addresses approximately the same issue, closing this ticket as a duplicate.
