beforeSubmit: ajax-loader visibility: visible ?

Pretty sure this is a bug, it makes the submit spinner visible when the page loads, before the form is submitted

beforeSubmit: function(arr, $form, options) {
                                $form.wpcf7ClearResponseOutput();
                                $form.find('[aria-invalid]').attr('aria-invalid', 'false');
                                $form.find('img.ajax-loader').css({ visibility: 'visible' });
                                return true;
                        },

Should be hidden
