Answer 1

I fixed this way. A patch for a jQuery Validation Plugin bug that it's not fixed even on v1.19.0

$('#save_edit_user').on('click', function () {
    var isValid = $("#edit_user").validate().form() && $("#edit_user").validate().element("#edit_user_email");
    //check current ajax call by $.active 
    //the form is not submitted before 0 ajax is running
    if (isValid && $.active == 0){
     // my save logic

    }
});
