A couple of navigation API tests rely on the `unload` event which is being deprecated

Rationale

Since unload event is being deprecated in chromium, we don't want to make these tests pass as is in chromium.
We can either:

• remove those tests from interop
• duplicate these tests, creating another version that uses pagehide instead of unload, and use the new tests in interop instead of these two.
• Keep chromium as failing these tests (we prefer not to)

@jgraham could you review this for Gecko?
@yulunwu2 / @gsnedders could you review this for WebKit?

Assuming these tests are providing useful coverage I think we should at least have pagehide versions in Interop.

Not a WebKit position, but a general comment:

Since unload event is being deprecated in chromium

Do you have any link to any spec issue about deprecating unload?

whatwg/html#6026 is the only issue I can find about deprecating it, but that hasn't seen any update since 2020; https://chromestatus.com/feature/5579556305502208 ("Deprecate unload event") links to whatwg/html#7915, which has had no updates since 2022.

If you're asking for tests to be removed from Interop, it would be much nicer to at least have a spec issue/PR to point at to justify why we no longer believe interoperability is worthwhile pursing for these tests.

Yea, those are the issues. Those tests are not very new... chrome currently doesn't intend to pass those . I think it would be more useful to have tests that rely on pagehide for interop 2026 that can actually be made interoperable, especially since the topic here is navigation API and unload deprecation is tangential.

Created web-platform-tests/wpt#59853 for the duplicate tests with pagehide. How do we make interop26 take those in and not the two existing ones from the OP?

Draft PR created. Once web-platform-tests/wpt#59853 is merged, we can merge web-platform-tests/wpt-metadata#8942
