e.g. ```js const registry = new CustomElementRegistry; const someElement = document.createElement('span', {customElementRegistry: registry}); someElement.innerHTML = `<span></span>`; ``` Then `someElement.querySelector("span").customElementRegistry` should be `registry` but it's `window.customElements` instead. This bug was caught by WPT with https://github.com/web-platform-tests/wpt/pull/53171
