Upstream service worker ext. event tests to WPT
The Web Platform Tests project includes equivalent versions of these
tests.
- `extendable-event-async-waituntil.html` - the version in WPT has been
extended with additional assertions, rendering the Chromium version
obsolete.
- `extendable-event-waituntil.html` - the version in WPT has been
extended to support (but not require) more rigorous compliance with
the specification. Update that test to be more precise and document
the expected failure in the Chromium infrastructure.
