Bug 217947

The following tests became flaky in WebKitGTK after r268604:

  http/tests/security/mixedContent/insecure-basic-auth-image.https.html [ Failure Pass ]
  http/tests/security/mixedContent/insecure-image-redirects-to-basic-auth-secure-image.html [ Failure Pass ]
  http/tests/security/mixedContent/secure-redirect-to-insecure-redirect-to-basic-auth-secure-image.https.html [ Failure Pass ]
  http/tests/security/mixedContent/secure-redirect-to-secure-redirect-to-basic-auth-insecure-image.https.html [ Failure Pass ]
  http/tests/security/mixedContent/secure-redirect-to-secure-redirect-to-basic-auth-secure-image.https.html [ Failure Pass ]

Actual output is similar in all tests. For instance:
