The most recent run passed.  Will adjust CL to mark test as flaky instead.

Mark serviceworker-echo-referrer-from-default-document.html as crashing on Mac.

Add test expectation that http/tests/fetch/referrer/serviceworker-echo-referrer-from-default-document.html will crash on Mac10.11 dbg.

This is also occurring on WebKit Linux (dbg) and WebKit Win7 (dgb). I'm going to mark the test as crashing there as well.

This test is also failing on several linux_site_isolation try jobs:
https://build.chromium.org/p/tryserver.chromium.linux/builders/linux_site_isolation/builds/1820
https://build.chromium.org/p/tryserver.chromium.linux/builders/linux_site_isolation/builds/1819
https://build.chromium.org/p/tryserver.chromium.linux/builders/linux_site_isolation/builds/1816

Since this CL just landed yesterday, maybe it should be reverted?  Or should we disable the test entirely?

Initially, I went for disabling the test because it failed only on a single builder.

If the failure is more wide-spread, and it is acceptable practice in Blink to revert CLs due to test failures (is it?), then I'm fine with reverting (with running tryjobs), although yhirano@ told me he would look at it first thing today.

[Fetch API] Abort fetching when the passed ScriptState is invalid.

Sometimes GlobalFetch::fetch is called with an invalid ScriptState.
Do not start fetching in such a case.
