在Chrome Signature-Pad中，只需打开空白页;在其他浏览器中工作正常

Question

Chrome 60.0.3112.113（64位）

macOS 10.12.6（16G29）

Signature-Pad 2.3.0演示页：（http://szimek.github.io/signature_pad）

几个月前，当我看着它时，Signature-Pad曾经工作过。 所以我实际上已经准备好尝试了，但现在发现它不起作用。

在Safari和Firefox中运行良好。

我清除了所有缓存并重置为默认值，但在保存时仍然只生成一个空白页面。任何想法如何解决？

控制台错误表示：http://szimek.github.io/signature_pad/js/app.js:33不允许导航顶部帧到数据URL：数据：图像/ PNG; BASE64，iVBORw0KGgoAAAANSUhEUgAABSQAAAJ8CAYAAADnFa9pAAAgAElEQVR4XuzdXch1WYIf9JWYSUCUmgqYuRCpaYNEjVJdXhhhopUWomMg1DReOGqgukVw8Ka7ZMDkxp7CG0PA6rrwQoxUNwQmF0J1Q4JRkerWBGbworrxAxGH6kZBE5CaFsHJGG35d589s2fP3uc5H3uvvfbavw0vb9XznrPXWr + 1nvM853 / WX + 8pLgIECBAgQIAAAQIECBAgQIAAAQIECFQS + D2VylEMAQIECBAgQIAAAQIECBAgQIAAAQIEikDSICBAgAABAgQIECBAgAABAgQIECBAoJqAQLIatYIIECBAgAABAgQIECBAgAABAgQIEBBIGgMECBAgQIAAAQIECBAgQIAAAQIECFQTEEhWo1YQAQIECBAgQIAAAQIECBAgQIAAAQICSWOAAAECBAgQIECAAAECBAgQIECAAIFqAgLJatQKIkCAAAECB ...

显然Google Chrome已取消对顶部框架导航的支持，您可以在此处查看更多信息：https://groups.google.com/a/chromium.org/forum/#!topic/blink-dev/GbVcuwg_QjM
