Comment (by mcsf):

 attachment:a11y-ui-improvements.diff includes ehgy's accessibility changes
 (see above), as well as UI improvements as
 [https://irclogs.wordpress.org/chanlog.php?channel=wordpress-
 dev&day=2014-03-28&sort=asc#m820791 discussed in IRC], namely:
 - Prefer a lighter UI.
 - Make the UI more coherent with the rest of the Customizer (button style,
 borders).
 - Don't hide the selected header, but rather highlight it. Adjust logic
 accordingly.
 - Stop the Customizer controls from jumping around when selecting a
 header.
 Plus:
 - Fix ordering of headers by defaulting timestamps to 0.
 - Force height for Randomize buttons instead of inferring it from other
 Header views.
 - Some removal of code.
