nextjs IE11 对象不支持“attachShadow”属

报错：SCRIPT438: 对象不支持“attachShadow”属性或方法

1、
package.json

// +
"@webcomponents/shadydom": "^1.7.4",
 "next-transpile-modules": "^4.0.2",

2、next.config.js

const withTM = require('next-transpile-modules');
// ...
    const originalEntry = config.entry;
    config.entry = async () => {
      const entries = await originalEntry();
      // add custom polyfills into specific next.js bundle
      // https://github.com/zeit/next.js/issues/10794
      const nextPolyfillPath = 'static/runtime/polyfills.js';
      const nextPolyfills = entries[nextPolyfillPath];
      if (nextPolyfills) {
        entries[nextPolyfillPath] = [
          nextPolyfills,
          './src/client/polyfills.js',
        ];
      }
      return entries;
    };
// ...
module.exports = withPlugins(
  [withTM],
  nextConfig,
);

3、add src/client/polyfills.js

// 如果报 shadydom.min.js
import '@webcomponents/webcomponentsjs';
import '@webcomponents/shadydom';
// 如果报 trunc 
import 'core-js/features/math/trunc';
