I think the point of the question is that unless you know how windowed aggregation works, it is a gotcha.
That's certainly a good way to describe it! Although this particular behavior is laid out in ANSI's definition, it's certainly not incredibly well documented elsewhere (and not mentioned per se on Ms' side), so I've actually seen it being disclaimed as "a bug".

Your lack of planning does not constitute an emergency on my part...unless you're my manager...or a director and above...or a really loud-spoken end-user..All right - what was my emergency again?
