False positive flagging "it's been" to "its been"

> **It's** been stuck in my head for weeks.

Maybe "been" also has some obscure noun sense? In any case here "it's" means "it has".

Start by reproducing the quoted “It's been stuck in my head for weeks” example in Harper and locate the rule or test that flags it. Done means this valid contraction is accepted while the intended “its” versus “it's” checks continue to work.
