nvrl 2128a2d705 fix(app): the highest episode row on screen no longer stretches to the window bottom
The watched and download buttons were laid out with with_layout(right_to_left,
Center), which takes every point of height the scroll area has left and
centres the buttons in it. Give the cluster the still's height instead.
