By "fix-up stuff", do you mean generate missing child(ren) or parent(s) (as stated in section 17.2.1 Anonymous table boxes/objects http://www.w3.org/TR/CSS21/tables.html#anonymous-boxes ) or do you mean something else? > This seems like a pretty useful heuristic.

I ask because this test Image as 'display: table-cell' http://test.csswg.org/suites/css2.1/20110323/html4/table-cell-002.htm is passed by Chrome 20.0.1132.57 and Opera 12.0.
