TIMEOUT on chromium by cross-origin issue

[makotoshimazu]

I'm trying to run wptrunner for chrome by the following command:

$ wptrunner  --processes=1 --product chrome --binary=./out/Master/chrome --metadata=~/tests/web-platform-tests --tests=~/tests/web-platform-tests --webdriver-binary=./out/Master/chromedriver /service-workers/service-worker/extendable-event-async-waituntil.https.html --log-raw=/dev/null --log-mach=-

and hit the following errors:

...
 0:05.66 TEST_START: Thread-TestrunnerManager-1 /service-workers/service-worker/extendable-event-async-waituntil.https.html
 0:25.66 TEST_END: Thread-TestrunnerManager-1 TIMEOUT, expected OK
...

All tests on extendable-event-async-waituntil.https.html are passed, but the page shows an error below.

Uncaught SecurityError: Blocked a frame with origin "https://web-platform.test:8443" from accessing a cross-origin frame.

I guess this problem is caused by running the "test-runner-harness.html" on HTTP.
Do you have any idea to run correctly?
