Restore the reference-theme direction: processing happens inline in the
filtered list, not on a separate page. The actual defect was the same
ticket being rendered twice (list row + form) while the bare <form><table>
inside <tbody> got foster-parented by the browser, displacing the extra
row info below the submit button. Now the processing ticket renders only
as the form, wrapped in a valid <tr><td colspan=6>, and every other row
renders normally.
