Theme Customizer sidebar needs to accommodate the scrollbar and be more horizontally flexible

A continuation from Myatu's comment on #19910:
CSS: Controls in the content column, ie .customize-control-select select make use of fixed widths, which do not account for a scroll-bar that may appear if the expanded content exceeds the height of the browser window.
Also, the scroll bar looks wonky
Since not everybody is using Webkit on OSX, where it only shows as an overlay while scrolling, we need to mind the scrollbar. The fixed-width layout is also problematic for longer labels, as can be expected in theme-added sections and translations.
