This looks great!

I would love to give Defuddle a try as a Readability replacement. However, for my use case I want to do in a Chrome extension background script (service worker). I have not been able to get Defuddle to work, while readability does (when combining with linkedom). So basically, while this works:

  import { parseHTML } from 'linkedom';
  ...
  private extractArticleWithReadability(html: string) {
      const { document } = parseHTML(html);
      const reader = new Readability(document);
      return reader.parse();
  }

This does not:

  import { parseHTML } from 'linkedom';
  ...
  private async extractArticleWithDefuddle(html: string) {
      const { document } = parseHTML(html);
      const result = new Defuddle(document);
      result.parse();
      return result;
  }

I get errors like:

- Error in findExtractor: TypeError: Failed to construct 'URL': Invalid URL

- Defuddle: Error evaluating media queries: TypeError: undefined is not iterable (cannot read property Symbol(Symbol.iterator))

- Defuddle Error processing document: TypeError: b.getComputedStyle is not a function

Is there a way to run Defuddle in a chrome extension background script/service worker? Or do you have any plans of adding support for that?
