#36083: Media Grid: 'wp-admin/upload.php' broken in nightly builds

 The media library view 'wp-admin/uploads.php' is not displaying properly
 in the nightly builds. It looks like the HTML is being rendered properly
 but there are missing CSS rules causing the problem.

 To reproduce:

 * Create a fresh install of WP
 * Add a few images to your media library
 * Update to latest nightly build (using beta tester plugin)
 * See the media library disappear on 'wp-admin/upload.php'

 Currently broken on (4.5-beta1-36808 but also yesterday).

 Interestingly, I can't reproduce this by building from source using `grunt
 build`, but I do see 938 lines of CSS missing from 'load-styles.php' on
 that page (with identical query vars), which is likely the cause.

 As an aside, it looks like some styles kick in that can make the grid
 appear when the viewport is shortened below 400px (see screencap:
 https://cloudup.com/iM4VzBnpfM5). I don't think that this is a problem,
 but can be confusing when debugging.
