"Rate it" shouldn't appear on a note which reader has already rated

[armchairancap]

Describe the bug

Rate it button appears for a CN which I've already rated.

Expected behavior

I should not be asked to Rate it if I've rated it. I can't always remember if I've already rated a particular note or not, especially since some posts may have several notes.

Screenshots

I get invited to rate a note:

But when I click on the button I get told I've already rated the CN. In this case there are additional notes, but maybe I don't want to rated additional notes, or there may be no additional notes.

Environment

Firefox (latest)
