[v4/blur/artwork-controller] Animate height change of artwork container + Remove text overflow title #9

Ideally the title in the now playing section can stretch over multiple lines. That however changes the height of the artwork container above, which makes for weird artwork transitions/animations. If we could animate the height change maybe it would make the transition better.
