Comment (by wppunk):

 Unfortunately, but the `5.9-beta2` broken the next code:

 {{{
 sanitize_key( 1 ); // The result was '1' in 5.8
 sanitize_key( 1 ); // The result is '' in 5.9
 }}}
 Probably, we should change the code:

 {{{
 if ( ! is_string( $key ) ) {
         $key = '';
 }
 }}}


 on:
 {{{
 if ( is_array( $key ) || is_object( $key ) ) {
         $key = '';
 }
 }}}
