Revert "Fix ResizeSensor/DomProps affecting component size diff"

This reverts commit 57e39e3.

This didn't actually affect the size diff, since we
compare the size of a single component, and not the size of the
test case as a whole. As a result, all other code outside of
the component is not factored into that size difference.
