This sounds exciting! When I read the following parts... > when the element comes in the viewport, remove the size cache and recompute the size. If the size has changed and the element is above the scrollTop, **adjust scrollTop to remove the jank of scrolling**. > when the size of an element above the viewport is changed the browser **changes the scrolltop to compensate**. ...I think there's some potential for weird scroll UX if `scrollTop` is adjusted by any significant amount. eg the track thumb could move out from under a user's mouse cursor. Also would want to make sure adjustments don't interfere with momentum scrolling.
