Edit modal=Native UI issues & fix

I’ve been testing out this plug-in (version 1.7.9) and for the most part it works perfectly. I noticed a slight UI issue that I’ve since patched.

The bug;
In your Edit Field Group set Edit modal to Native
When editing your gallery images click on the pencil icon to edit an image
>> This opens the native modal as expected
Closing the modal by way of the close icon (top right) or the ‘Insert into page’ button fails to close the ‘acf-gallery-backdrop’ overlay or unsets the scroll overflow on the page body.

The solution:
Edit the acf-photo-gallery-field.js file and adjust the code from line 119 onwards to add the close and submit buttons to the existing code.

My updated code is;

$(document).on('click', '#acf-photo-gallery-metabox-edit .acf-edit-photo-gallery button.button-close, div.media-modal button.media-modal-close', function() {
        var id;
        id = $(this).attr('data-close');
        $('#acf-photo-gallery-metabox-edit #acf-photo-gallery-metabox-edit-' + id).fadeOut('fast');
        $('.acf-gallery-backdrop').remove();
        $('body').css('overflow', 'auto');
        return false;
    });
	
    $(document).on('click', '#acf-photo-gallery-metabox-edit .acf-edit-photo-gallery button.button-primary, div.media-modal-content  button.button-primary', function() {
        var button, field, data, post, attachment, action, nonce, fieldname, form = {};
        button = $(this);
        url = $(this).attr('data-ajaxurl');
        action = 'acf_photo_gallery_edit_save';
        attachment = $(this).attr('data-id');
        fieldname = button.attr('data-fieldname');

        $('div.acf-photo-gallery-group-' + fieldname + ' #acf-photo-gallery-metabox-edit-' + attachment + ' .acf-photo-gallery-edit-field').each(function(i, obj) {
            if (obj.name == 'acf-pg-hidden-action') {
                form['action'] = obj.value;
            } else if (obj.type == 'checkbox') {
                if ($(this).prop("checked")) {
                    form[obj.name] = obj.value;
                } else {
                    form[obj.name] = null;
                }
            } else {
                form[obj.name] = obj.value;
            }
        });

        button.attr('disabled', true).html('Saving...');
        $.post(url, form, function(data) {
            button.attr('disabled', false).html('Save Changes');
            $('#acf-photo-gallery-metabox-edit #acf-photo-gallery-metabox-edit-' + attachment).fadeOut('fast');
            $('.acf-gallery-backdrop').remove();
            $('body').css('overflow', 'auto');
        });
        return false;
    });
