---------------------------+--------------------
 The `wp_set_current_user()` function returns early if the function is
 called with the current user ID to avoid the work of switching users when
 it's not required.

 However, the function uses a type strict comparison when determining if
 the user ID is the same, so `wp_set_current_user( (int)
 get_current_user_id() )` will return early, whereas `wp_set_current_user(
 (string) get_current_user_id() )` will proceed through the set up of the
 new current user.

 Introduced in r57882 for #60700.

 This is a minor fix (tests and PR incoming) so I've put it on the 7.0
 milestone.
