Revert r154544 to make dynamicly resizing framesets work again.

Credit to srinivasa.ragavan.venkateswaran@intel.com for preparing
the original patch:
https://codereview.chromium.org/51033003/
and thus bringing this to my attention.

It's not clear that both branches are necessary here.
The frameset one is clearly needed, the bodyTag branch hopefully
is not, but I'm just reverting the whole change for now.
