Description Chris Dumez 2022-07-27 09:00:32 PDT

WorkerGlobalScope.isSecureContext should be based on owner's top-level creation URL, not the owner's URL:
- https://html.spec.whatwg.org/multipage/webappapis.html#secure-context

This means that if a worker created in a HTTPS iframe, under a HTTP top-level document should not be considered as secure.

This is causing us to fail the "HTTPS worker from HTTPS subframe" subtest on secure-contexts/basic-dedicated-worker.html WPT test. This test is passing in both Gecko and Blink.
