Automatic update from web-platform-tests
Fetch: Plumb request initiator through passthrough service workers.
This CL contains essentially two changes:
1. The request initiator origin is plumbed through service workers
that do `fetch(evt.request)`. In addition to plumbing, this
requires changes to how we validate navigation requests in the
CorsURLLoaderFactory.
2. Tracks the original destination of a request passed through a
service worker. This is then used in the network service to force
SameSite=Lax cookies to treat the request as a main frame navigation
where appropriate.
For more detailed information about these changes please see the
internal design doc at:
https://docs.google.com/document/d/1KZscujuV7bCFEnzJW-0DaCPU-I40RJimQKoCcI0umTQ/edit?usp=sharing
In addition, there is some discussion of these features in the following
spec issues:
https://github.com/whatwg/fetch/issues/1321https://github.com/whatwg/fetch/issues/1327
The test includes WPT tests that verify navigation headers and SameSite
cookies. Note, chrome has a couple expected failures in the SameSite
cookie tests because of the "lax-allowing-unsafe" intervention that is
currently enabled. See:
