Still flaky: https://travis-ci.org/ampproject/amphtml/builds/245881991

Edit: Unless the source of the failing tests lies elsewhere? @jridgewell?

I think amp-bind tests don't run on Saucelabs with Justin's change. These are the errors in the build above (hard to read w/o colors):

Safari 9.1.2 (Mac OS X 10.11.6) error page "before each" hook for "should show the body in error test" FAILED
Timeout waiting for elements to start loading.

Safari 9.1.2 (Mac OS X 10.11.6) test extensions loading in multiple orders one extension, extension loads first, all scripts in header FAILED
Timeout waiting for elements to start loading.

Chrome Mobile 44.0.2403 (Android 6.0.0) amp-pixel amp-pixel integration test "before each" hook for "should keep referrer if no referrerpolicy specified" FAILED
Error: timeout of 10000ms exceeded. Ensure the done() callback is being called in this test.

Changing this issue to track re-enabling of amp-bind integration tests on Saucelabs.

Browser-specific flakiness in <amp-form> integration test:

• This only affects Edge and Safari 9, but is fine on Chrome, Firefox and Safari 10.
• Not caused by a race with AmpFormService registration.
• Might have to do with expected user errors.

These tests are running on SL.
