If our goal is to match other browsers, we need to test them, not read the docs. MSDN often bears little relation to IE's actual behavior.

Sure it's possible. We can test every CSS property and every HTML element. It should be easy to write a test case that checks every case exhaustively. I don't think it makes sense to change our behavior based on a guess of what other browsers do.
