* Filters the CSS classes for the body tag in the admin.
* This filter differs from the {@see 'post_class'} and {@see 'body_class'} filters
* in two important ways:
* 1. `$classes` is a space-separated string of class names instead of an array.
* 2. Not all core admin classes are filterable, notably: wp-admin, wp-core-ui,
* and no-js cannot be removed.
