304095@main, which reverted 304095@main and 304390@main, reduced RenderStyle by 8 bytes. 305612@main removed a CanMakeCheckedPtr inheritance from RenderStyle. This change gets RenderStyle 8 bytes back. I have confirmed that these two changes fixed the MotionMark regression of bug 305085. So 304095@main and 304390@main can be re-landed. But we need to ensure that the size of RenderStyle will not be affected when changing PublicPseudoIDBits.
