Summary REGRESSION (r261841): Scrolling on Spotify page gets reset to the top

Load https://open.spotify.com/artist/6vWDO969PvNqNYHIOW5v0m and scroll down. Note that when new content gets added to the bottom, the scroll position is reset to the top. What's happening is that the <div> with overflow:scroll is getting resized to some large, non-scrollable size for a while, triggering a reset of the scroll position via RenderBlock::endAndCommitUpdateScrollInfoAfterLayoutTransaction()/updateScrollInfoAfterLayout(). This doesn't happen prior to r261841. The page does hit the new code.
