It's weird to be changing behaviour in a refactor change. This should be moved
to a separate patch.
Also should there be updates to test cases if it's changing?

             ASSERT_NOT_REACHED();
     }
     state.style()->setWillChangeContents(willChangeContents);
     state.style()->setWillChangeScrollPosition(willChangeScrollPosition);
     state.style()->setWillChangeProperties(willChangeProperties);
     state.style()->setSubtreeWillChangeContents(willChangeContents || state.parentStyle()->subtreeWillChangeContents());
 }
