Comment (by TobiasBg):

 I think I know what I did here... My 3.8 test install was not on 3.8
 anymore, for some reason... So, you are right. This does not happen on 3.8
 and is therefore not a regression. The colors/wp-admin.css merge did not
 break anything here. I guess the tabs without the bottom border just
 looked weird to me. So, that part of the ticket is invalid. Sorry for the
 confusion.

 However, while investigating this, I noticed another minor glitch (also
 not a regression, so no top priority), which is easy to fix: When the
 `.nav-tab-active` is in the bottom row of stacked tabs, the background of
 the non-active tabs spills into the active tab, as it's transparent. Its
 background color should simply become the same color as the bottom border.
 See the attached screenshot.

 Finally, we have the background in the old media upload thickbox (which
 you can confirm, if I understand correctly).

 So, the new [attachment:27116.3.patch] fixes that and the (newly
 discovered) `.nav-tab-active` glitch.
