Comment (by joedolson):

 I think that the most reasonable resolution to the media icons is to
 remove the background image and replace with dashicons. Dashicons render
 in high contrast mode, so they would allow that context to be visible.

 I've done a quick test of concept, and it works just by adding dashicons
 classes to the relevant items, and adding a :hover/:focus state that
 changes the icon out when focused. There would be some clean-up required
 to remove obsolete CSS, and it's possible that the background sprite would
 no longer be in use afterwards. I'm not seeing another use of it in media-
 views.css, but I haven't explored more broadly yet.

 I can do a partial patch for this, but the swap to dashicons would require
 some CSS changes to clean up the design that I'm not confident of.
