Nika is this something you want to fix on fission or can we disable the test?

The specific assertion here is related to session history, so redirecting to peter.

Please disable this test for fission, adding kmag as the reviewer.

To be kept open until this test is fixed for fission.

https://hg.mozilla.org/mozilla-central/rev/f3a439325b98

The test itself passes and we getting session history working in Fission will take time.
So we could add SimpleTest.expectAssertions(0, 3);
But there is another bug 1580391 which is trickier. The underlying issue seems to be bug 1586793.

I don't think session history in the parent will be done in M4.1.

This test got re-enabled for Fission by kmag in Bug 1586911.
