Comment (by isabel_brison):

 In [changeset:"52380" 52380]:
 {{{
 #!CommitTicketReference repository="" revision="52380"
 Fix deprecated usage of passing null to explode()

 As of PHP 8.1, explode() does not permit null as its second argument. This
 results in warnings being spat out on every page because of a usage of
 this in wp-includes/block-supports/layout.php.

 See #53635.
 Props noisysocks.
