Quick hack to make popup shrinkage work again

The upstream change to make popup shrinking work properly is a big project, so I'm doing a quick hack here so that we don't ship more builds with it broken.

BUG=30291
TEST=Install news sample extension. Expand a section, then contract it. Popup should contract too.

RenderView::OnEnablePreferredSizeChangedMode() {
What kind of renderers is this enabled for? I think I remember seeing that this
is enabled for all tab on the Mac. I wonder how bad it will be to wake up the
CPU every 10ms to check every tab.
