[Spec issue] How a cell's height is set

Hello all,

I am encountering more and more tests where an HTML table cell's height
is set in a test and where implementation diverges causing a reftest to
be impossible to create (e.g.:
http://test.csswg.org/suites/css2.1/nightly-unstable/html4/table-layer-transparency-006.htm
). Fixing this spec issue should be a high priority.
