1652556 - [meta] Fix failing cross-origin mochitests with Fission enabled

Status: RESOLVED FIXED

(Testing :: Mochitest, task)

Tracking this meta bug for Fission M6c Nightly because we want Fission to pass all these xorigin mochitests before we enable Fission in Nightly. The bugs for individual test failures may be fixed for Fission M6b or M6c.

Some xorigin mochitests fail only with Fission disabled for both Fission and non-Fission, indicating a bug in non-Fission code or in the test itself. The Fission team does NOT plan to fix those non-Fission xorigin failures because we will only run the xorigin mochitests with Fission enabled.

Chris, some correction:
We will need to look into the tests that are failing only when Fission is disabled because their passing on Fission-enabled smells like a false positive that needs to be looked into and fixed. The ones that the Fission team will not focus on fixing are the tests that are failing with cross-origin enabled only (i.e. no explicit Fission mode setting). Those are tracked at https://docs.google.com/spreadsheets/d/16G5AZhHWWow3rBgim4QBHzWXMIIJiky2SzXYgDMTTKY/edit#gid=1259287422 .

Moving the meta bug to later but the individual tests should be fixed for Fission Nightly (M6b) if those expose broken features or in M7 (beta) if they are because of test issues.

The remaining Fission xorigin Mochitests failures are:
dom/security/test/mixedcontentblocker/test_frameNavigation.html (Bug 1353608) - M-Future
layout/base/tests/test_bug603550.html (Bug 1677543) - M-Future

Closing this bug as all M7 blockers are resolved.
