Now I'm thinking that the reason RenderTableSection's cell children flex code doesn't run is that percentHeightDescendants doesn't ever include this image element.

In http://trac.webkit.org/changeset/36513, Dan wrote this comment about code in RenderBox that adds to that list:

(WebCore::RenderBox::calcReplacedHeightUsing): Changed to skip over
anonymous containing blocks, if any, and when that happens, use
addPercentHeightDescendant() to ensure that the non-anonymous block
is aware of the dependent percent-height box.

In this case, because the containing block is never an anonymous block, we never add the image element to any RenderBox's list.  I tried an experiment in RenderBox::computeReplacedLogicalHeightUsing to change that loop to a do while loop so the first containing block calls addPercentHeightDescendant even if its not an anonymous block.  Again, this experiment fixed the original problem -- and broke the last test case in my attachment horribly.  So maybe I'm off in the weeds here.
