The DOM Fission team is relying on feature teams to debug and fix Fission failures in their tests. If the failure looks like a bug in Fission's DOM or IPC changes, you can send the bug back to me.
We're hoping to enable Fission for a subset of Nightly users in early Q3, so we would like WPT tests to be green for Fission by end of Q2. Whether a particular test failure actually blocks shipping Fission is up to the discretion of the feature team. You all would know better than the DOM Fission which test failures are most important.
You can enable Fission when running WPT tests locally using mach wpt --enable-fission
.

Sorry about that! I commented before the --enable-fission flag was merged to mozilla-central. The flag has now been merged and I see it in mach help wpt
:
--enable-fission Enable fission in Gecko (defaults to disabled).
--no-enable-fission Disable fission in Gecko.

When running this test under Fission, I saw this error UnknownError: SecurityError: Permission denied to access property "windowUtils" on cross-origin object
and I guess this might be the root cause.
The result of reftest is like following, so I guess the test fails due to the above reason and we haven't started the comparasion yet.
REFTEST IMAGE 1 (TEST): data:image/png;base64,
REFTEST IMAGE 2 (REFERENCE): data:image/png;base64,

Chris, when looking at the test it seems it is doing a history.back() within a data: URI iframe [1]. A more generic questions, what's the state of data: URIs with fission at the moment? Is it possible that we are ending up in the wrong process when doing a history back on a data URI?

Peter, do you know the current state of data: URIs and history with Fission?

I think this SecurityError is Marionette bug 1574508.
