 * Hi there,
 * With Version 5.9.6, I noticed an error in events-manager/includes/js/events-manager.
   js
 * which was, on one of my websites (but not another), throwing an error that prevented
   locations from being added – map would not load.
 * I traced this to line 1032:
    `if( $(this).prop('readonly') === true ) return;`
 * Changing this to:
    `if( jQuery(this).prop('readonly') === true ) return;`
 * solves the problem.
