Instead of trying to arrange things so that there is something covering all the parts of the scrollable area we don't want to see, use -webkit-image-mask to only show the parts we do want to see.

This change also fixes overflow of miniview items. Under some circumstances, the old JS approach wasn't working. Used a CSS one instead.

TEST=Set up most visisted so that it has items. Start it in
expanded mode. Minimize it. There should be no clipped last
item.
