1589814 - Controlled pages should be uncontrolled after "clear-site-data: storage" directive, re-enable clear-site-data/storage.https.html WPT test.

Status: RESOLVED DUPLICATE of bug 1837276

(Core :: DOM: Service Workers, defect, P2)

Description

[Andrew Sutherland [:asuth] (he/him)]

https://github.com/web-platform-tests/wpt/pull/19132 updated the clear-site-data/storage.https.html test to verify that after "clear-site-data: storage" has wiped the storage for an origin, previously controlled pages should no longer be controlled. We had previously expected failures for parts of the test, and in bug 1456995 we disabled the test entirely.

WPT results for this are at: https://wpt.fyi/results/clear-site-data/storage.https.html?label=experimental&label=master&aligned

This is new behavior as far as Firefox's built-in sanitizer affordances because I believe in those cases we attempt to close the impacted tabs in question. Or we need to improve our Firefox-specific tests...

I think all of the enhancements required are inside ServiceWorker code, but cc'ing relative security/privacy people as an FYI.

I'm going to dupe this forward to bug 1837276 since I put a useful analysis there and :twisniewski provided some good contextual motivation to expedite this fix for consistency with Webkit having made the behavioral change (although the spec work is still in flight and unfortunately I think unowned at this stage).
