LayoutTest http/tests/security/contentSecurityPolicy/upgrade-insecure-requests/basic-upgrade-cors.https.html is a flaky timeout

Seeing this frequently on Sierra Release WK2

First instance on Sierra was ~r207027 according to the flakiness dashboard.

Comment 2 Alexey Proskuryakov 2016-10-17 15:33:40 PDT

It also asserts a lot in debug builds. Seems worth looking into soon.

Comment 4 Ryan Haddad 2016-10-18 17:15:17 PDT

Marked test as flaky on Sierra Release WK2 in http://trac.webkit.org/projects/webkit/changeset/207506

Comment 5 Alexey Proskuryakov 2016-11-15 11:50:08 PST

Is the timeout still happening after the assertion fix?
