It could very well be that I got something wrong about spaces. Unfortunately, I don't have much time right now to dive into this, so it has to wait until next week. But we should probably start by analyzing the spec to see what the real behaviour should be. Please update the Wiki if you find the right references. Thanks and sorry for not immediately addressing it.
