 Problem:

 The HTML API is a complex and important feature being implemented by a
 small group of developers. The implementation follows the HTML Standard
 https://html.spec.whatwg.org/.

 The tests and the implementation of the HTML API both depend on the
 interpretation of the standard by the same small group of developers. This
 means there is a risk of misinterpretation or overlooked edge cases.

 Needs:

 A suite of tests that can serve to test the HTML API that does not depend
 on our own interpretation of the HTML Standard and is implementation
 agnostic.

 Benefits:

 Many software projects such as browsers implement the HTML Standard. We
 should be able to use a third-party implementation-agnostic test suite to
 validate our implementation of the HTML API. This mitigates the risk where
 our implementation and tests all derive from the same interpretation of
 the specification.
