Looking at WPTs, it seems like Firefox is passing most of
them: https://wpt.fyi/results/fetch/compression-dictionary?label=experimental&label=master&aligned
Do you know if they shipped with these updates? Are there tests for
these updates?
Note that these WPT tests are for compression dictionary transport in
general. This has been implemented in Firefox
(https://bugzilla.mozilla.org/show_bug.cgi?id=1882979) and WebKit
(https://bugs.webkit.org/show_bug.cgi?id=295249) recently, after RFC was
ratified but while the HTML and fetch PRs were still under review. Some
spec clarification happened during that period and a lot of new tests
added but mostly they follow what Chromium ships. I can't speak for
Mozilla, but at Igalia, we have been closely following the spec/tests
changes and once the runtime flag is enabled WebKit should also pass
most of the tests.
Now regarding the updates, as I mentioned in the intent to ship,
specific tests for them are:
https://wpt.fyi/results/fetch/compression-dictionary/fetch-destination.tentative.https.html
https://wpt.fyi/results/fetch/compression-dictionary/dictionary-fetch-with-link-element-crossorigin.tentative.https.html
https://wpt.fyi/results/fetch/compression-dictionary/dictionary-fetch-with-link-referrer-and-referrerpolicy.tentative.https.html
Chromium will pass all these tests when updates are shipped and so will
WebKit once the runtime flag is enabled.
I see Firefox is only failing request destination, I opened
https://bugzilla.mozilla.org/show_bug.cgi?id=2077064 so they have it
tracked.
