I now have a better understanding, and indeed you're right. It's actually exactly the same situation as the one in non-dynamic case, but because the offset is negative *and* dynamic, the choice is incorrect. Which makes me think that in both cases, if we have the choice between two object with the same size + offset value, then choosing the one with the larger offset solves the issue. I'll check that.
