DOMParser test

This is a visual test page for using a DOMParser for all included content (even partial HTML documents).

Visual inspection isn't sufficient.

Check in the DOM Inspector that all expected content is inserted and no unexpected content is (e.g. <body> or <main> elements).
Check in the Console that no unexpected errors are thrown, and that appropriate warnings are logged.

Partial HTML document

This is the backwards-compatibility case. It should NOT insert a <body> element

It should insert "document.body.innerHTML" It should NOT insert a <body> element

It should insert "document.querySelector('main').innerHTML" It should NOT insert a <main> element

It should NOT insert ANYTHING because it fails to find the fragment
