Which document?  The node document of the element passed to `getComputedStyle`, or the document the style is being computed in (that is, the document of the window which was the `this` for the `getComputedStyle` call)?

"The document" (which one, per above), or "a document" or "a document that has a browsing context"?  I'm pretty sure they compute style for an element that is in its node document's document tree if that node document has a browsing context.  Dunno what they do if you `getComputedStyle` on something in an XHR `responseXML`, say.
