Some changes in this CL are actually revert of
https://codereview.chromium.org/2575653002/. Now use the new flag for the
functionality (invalidating all paint properties before/after printing).

   // TODO(ojan): Merge this with IntersectionObserver once it lands.

   void clearScrollAnchor();
   bool shouldPerformScrollAnchoring() const override;
   void enqueueScrollAnchoringAdjustment(ScrollableArea*);
