Yes, this is how Chrome behaves (assuming you are on HTTPS).

Who are you referring to with "You" here. The people you're talking to
(Martin and I) both work on Firefox, and we'd be more than happy for
Chrome to behave the way that Firefox does.

here is the security document, which specifically contemplates
persistent consent.
