WP eSignature Plugin - Fix for line breaks in textareas

signdoc.js

(function ($) {

    $(document).ready(function () {
        makeSignatureKeyboardAccessible();
    });

    function makeSignatureKeyboardAccessible() {

        var signaturePopup = $('.signature-wrapper-displayonly');

        if (signaturePopup) {
            signaturePopup.attr('tabindex', 0);
        }

        $(document).on('keypress', signaturePopup, function (e) {
            var code = e.keyCode || e.which;
            var tag = e.target.tagName.toLowerCase();

            if (code == 13 && tag != 'textarea') {
                signaturePopup.click();
            }
        });
    }

})(jQuery);

I added line 17 in the above code and modified line 19.
