I've filed a bug to enable setting the scroll chai

| + assert_equals(0, remainingNumberOfTimesToBeCalled); |
| + for (var i = 0; i < elementCount; ++i) |
| + assert_equals(elements[i].creationOrder, elements[i].calledOrder); |

| + |
| +test(function() { |
| + var scrollState = new ScrollState(100, 0, 0, 0, 0, false, false); |
| + window.internals.setScrollChain(scrollState, []); |
| + assert_equals(0, remainingNumberOfTimesToBeCalled); |
| + scrollState.distributeToScrollChainDescendant(); |
| + assert_equals(0, remainingNumberOfTimesToBeCalled); |
