The pattern has no patternUnits or patternContentUnits specified, which means the former defaults to objectBoundingBox and the latter defaults to userSpaceOnUse per spec. Since the relevant markup is: <pattern id="testPattern" width="100" height="100" viewBox="0 0 100 100"> <rect width="100" height="100" fill="blue" /> </pattern> <rect fill="url(#testPattern)" x="240" width="100" height="100" /> this defines a pattern that's 10000x10000px which has a single 100x100 blue square in it. Then we fill with that pattern... the only question is what that should do. I assume the test meant to use patternUnits="userSpaceOnUse", but it doesn't actually do that.

There are 14 shapes now. I think Microsoft has changed the test though. The original test should be fixed by the check in for bug 633337.
