We recently enabled WPT on Fennec, and as part of that, had to skip some frequent intermittently failing tests to get a mostly-green run. Filing this bug to track hopefully fixing whatever flakiness is causing the intermittent failures so these tests can be reenabled. Running the tests locally on repeat, these ones failed intermittently: content-security-policy/navigate-to/child-navigates-parent-blocked.sub.html : TIMEOUT 4 out of 5 attempts content-security-policy/navigate-to/unsafe-allow-redirects/allowed-end-of-chain-because-of-same-origin.sub.html : TIMEOUT 3 out of 5 attempts content-security-policy/navigate-to/unsafe-allow-redirects/allowed-end-of-chain.sub.html : TIMEOUT 1 out of 5 attempts content-security-policy/navigate-to/unsafe-allow-redirects/blocked-end-of-chain.sub.html : TIMEOUT 1 out of 5 attempts

Pushed by wkocher@mozilla.com: https://hg.mozilla.org/integration/autoland/rev/d9dd441d53fd Update test annotations for fennec wpt csp/navigate-to/ a=testonly

Wes: This had leave-open, then something landed, and now it's not 'leave-open'. Does that mean it can be resolved? Or is there something more here? Firefox does not currently support CSP navigate-to -- these tests should be skipped or annotated as expected fail.

This is not resolved, imo, though I don't have any strong feelings about keeping this bug open if that's problematic for triage in this component. I had to skip these tests (rather than just annotate as failing) on android because they were frequently randomly failing in ways other than the expected (crash, timeout, notrun, etc), annotated failures expected. Having the tests disabled (rather than annotated as expected failures) means we won't see if something starts making the tests pass (expected because we start supporting the feature or unexpected because something randomly tweaks things in ways that make the tests start passing). In this case, though, we would probably see those changes based on the desktop tests, so if you want to resolve the bug, I won't stop you.

In that case we just move it into the backlog for now - thanks!
