Comment:

 In [changeset:"50490" 50490]:
 {{{
 #!CommitTicketReference repository="" revision="50490"
 Roles/Caps: Return same result from `current_user_can` and `user_can()`.

 Ensure `current_user_can()` and `user_can()` return the same results for
 logged out users. For core capabilities this changes `user_can( 0, 'exist'
 )` to return `true` rather than `false` in line with `current_user_can(
 'exist' )` for logged out users.

 Convert `current_user_can()` and `current_user_can_for_blog()` to wrapper
 functions ultimately calling `user_can()`.

 Add anonymous user to primitive capability checks as appropriate. Convert
 `Tests_User_Capabilities::test_other_caps_for_all_roles()` to use a data
 provider and add tests to check whether user exists in the database
 (`WP_User::exists()`) as that intentionally differs from the `exist`
 capability.

 Props jjj, johnbillion, peterwilsoncc, SergeyBiryukov, TimothyBlynJacobs.
 Fixes #52076.
