[scoped-custom-element-registry]: whenDefined() doesn't work when already defined

[lazka]

<script type="module">
import 'https://jspm.dev/@webcomponents/scoped-custom-element-registry/scoped-custom-element-registry.min.js';

class SomethingDifferent extends HTMLElement {}

customElements.define('something-different', SomethingDifferent);

customElements.whenDefined('something-different').then(() => {
    console.log("works"); // this doesn't get called
});
</script>

• whenDefined promise doesn't do anything if the element was defined before
• without the polyfill this works as documented
