Changeset 39588 for trunk/src/wp-includes/capabilities.php

Message:

Multisite: Handle capability check for removing oneself via map_meta_cap().

Site administrators should not be able to remove themselves from a site. This moves the enforcement of this rule from wp-admin/users.php to remove_user_from_blog() via the remove_user capability, which furthermore allows us to get rid of two additional clauses and their is_super_admin() checks in wp-admin/users.php. A unit test for the new behavior has been added.

Fixes #39063. See #37616.
