I have marked this as failing while this issue is investigated.

I am able to reproduce this issue with r258432 by running the command below.

run-webkit-tests --iterations 1000 --exit-after-n-failures 3 --force -f http/tests/security/mixedContent/insecure-worker-global-scope.html

[5/1000] http/tests/security/mixedContent/insecure-worker-global-scope.html failed unexpectedly (text diff)
[6/1000] http/tests/security/mixedContent/insecure-worker-global-scope.html failed unexpectedly (text diff)
[7/1000] http/tests/security/mixedContent/insecure-worker-global-scope.html failed unexpectedly (text diff)
Exiting early after 3 failures. 4 tests run.


1 test ran as expected, 3 didn't (996 didn't run):

Comment 4 Jason Lawrence 2020-03-13 17:05:36 PDT

Reverted r258446 for reason:

These expectations are no longer needed.
