Ah, object-position isn't on my radar yet.

I would argue that it was a mistake infecting object-position with the same virus that background-position has.

Nope, 'object-position' has the same problem.

Most other places that use <position> don't show the problem because,
as you pointed out previously, the "subject" being positioned is 0x0
anyway, so percentages go back to acting the same as lengths.
