Filter::widget() opened <table id="fieldsTable"><tbody> and returned
without closing either. On the filter view the parser recovered because
the next sibling was another <table>, but on the events page the
following </div> closed the toolbar column while the table stayed open,
so the remaining toolbar columns were foster-parented out of place.
