Comment (by SergeyBiryukov):

 In [changeset:"48980" 48980]:
 {{{
 #!CommitTicketReference repository="" revision="48980"
 Code Modernization: Return an empty string from `wpdb::_real_escape()` if
 a non-scalar value is passed.

 This avoids a fatal error on PHP 8 caused by passing a non-string value to
 ` mysqli_real_escape_string()`, and maintains the current behaviour.

 See #50913, #50639.
