Comment (by feedmeastraycat):

 This is also affected when you register a new user with & in the e-mail.
 Registering a user with "foo&bar at example.com" is registered in the
 database as "foo&bar at example.com" thus failing a test on
 `email_exists( 'foo&bar at example.com' )` (which returns false) and
 `get_user_by( 'email', 'foo&bar at example.com' )` (which also returns
 false).
