Update style for body when viewport defining element changes.
Whether the body box has scrolling overflow or not depends on the
computed overflow of the html element.
The HasOverflowClip flag, along with creating and removing a paint
layer on LayoutBlock is updated as part of SetStyle. However, if the
html element is recalculated, its overflow changing causing the
viewport defining element to change, but body did not need a recalc,
the overflow clip flag and paint layer is not updated for body.
This CL forces a SetStyle on the body LayoutObject to trigger the
necessary update after recalc when when the viewport defining element
changes.
This fixes scrollingElement.html in wpt/cssom-view.
