[ShadyCSS] Cannot load the polyfill async #33

Open ebidel opened 8 years ago

ebidel commented 8 years ago

I'm trying to load the polyfills conditionally, async and am not able to shim styles.

http://jsbin.com/qaxifecapa/edit?html,output works in Canary, but not in other browsers.

If you uncomment the <script> tags in that jsbin that load the polyfills and replace this:

lazyLoadWCPolyfillsIfNecessary().then(function(events) {
  if (!supportsShadowDOMV1) {
    ShadyCSS.prepareTemplate(CardSwiper.template, CardSwiper.is);
  }
  window.customElements.define(CardSwiper.is, CardSwiper);
});

with:

ShadyCSS.prepareTemplate(CardSwiper.template, CardSwiper.is);
window.customElements.define(CardSwiper.is, CardSwiper);

then the demo works as expected.

Sometimes I get the error "window.customElements" is not defined. There seems to be a dep on CE in this polyfill.
