Comment (by SergeyBiryukov):

 In [changeset:"49007" 49007]:
 {{{
 #!CommitTicketReference repository="" revision="49007"
 Tests: Fix the failures in REST API `format` keyword validation tests on
 PHP 8.

 The tests ensure that `rest_sanitize_value_from_schema()` and
 `rest_validate_value_from_schema()` throw an "undefined offset" notice
 when the required `type` schema keyword is not passed.

 In PHP 8, that notice is now a warning, so the tests need to be adjusted
 accordingly.

 Follow-up to [48300], [48993].

 See #50913.
