verify / ensure proper serialization of shadow roots excluding closed shadow roots from getInnerHTML

[thescientist13]

Type of Change

• New Feature Request

Summary

Just want to make sure I'm properly handling HTMLElement.getInnerHTML for?

• closed shadow roots
• serialization

getInnerHTML(options = {}) {
  return options.includeShadowRoots
    ? `
      <template shadowroot="${this.shadowRoot.mode}">
        ${this.shadowRoot.innerHTML}
      </template>
    `
    : this.shadowRoot.innerHTML;
}

Details

Coming out of #19 and made a repo for testing, since it appears I might be taking some serious liberties with the implementation here. 😅

Somewhat related to this, not sure if there is value in having a way to opt-out at the top level for this, like if your page is a custom element? Perhaps you want your page as light DOM, but still keep the shadow DOM for all nested children?

edit: to the above, I just recently pulled a feature called lightMode since I realized a better way to output non shadow content was to just let user's opt-out by using innerHTML. But in relation to this, if say someone is using a third party library and wants that library rendered without Shadow DOM (obviously mileage will vary vastly on this from lib to lib) but then that's a way to bring that config back?

Looks like this will get full resolved between #171 and #178
