 When using js rest api to save page.

 Duplicate value test in wp-includes/rest-api/fields/class-wp-rest-meta-
 fields.php line 303 fails and causes error "Could not update meta value in
 database."


 {{{
 if ( $old_value[0] === $meta_value ) {
 }}}



 Problem seems to be that $old_value is not going through wp_slash but new
 $meta_value is.

 I get it working by changing code to test against $value instead.

 {{{
 if ( $old_value[0] === $value ) {
 }}}
