I see this test was disabled for non-e10s windows in bug 1381932, but this specific failure is a mix of e10s and non-e10s (primarily e10s).

there is a pending needinfo here as we disabled the test, I assume there will be a desire to re-enable this and get it reliable.
Clearly ni on Jet as he no longer works at Mozilla.
