Comment:

 In [changeset:"47777" 47777]:
 {{{
 #!CommitTicketReference repository="" revision="47777"
 Administration: Avoid a PHP 7.4 notice in `add_meta_box()` when attempting
 to re-add a previously removed box.

 The logic for skipping previously removed meta boxes with the `core`
 priority should also apply to the `sorted` priority that is used when the
 boxes were manually reordered.

 Add a unit test.

 Props coolmann, franzarmas, SergeyBiryukov.
 Fixes #50019.
