HTMLTemplateElement toString does not include contents

https://github.com/WebReflection/linkedom/blob/ec5ce8470c50fe2e9ea6e8b339e6ee4f23077c73/esm/html/template-element.js#L19

I see that this related issue is marked as closed https://github.com/WebReflection/linkedom/issues/21

But later modifications removed this functionality

I am using this hack locally to get the functionality I need

  const originaltoString = Object.getOwnPropertyDescriptor(Element.prototype, 'toString')!
  Object.defineProperties(HTMLTemplateElement.prototype, {
    toString: {
      value() {
        return (
          originaltoString.value
            .call(this)
            .replace(/<\/template>$/, this.content.childNodes.join('')) + '</template>'
        )
      },
    },
  })

Start at esm/html/template-element.js around line 19, where HTMLTemplateElement.toString is defined. Compare its output with the behavior described in the issue and the provided local workaround. Done means toString includes the template contents before the closing tag.
