Pulse the Review button when a comment is added to a review

Feature Description

As a new user unfamiliar with pull request reviews, I would like the Review button to have a visual indicator (like a pulse) each time a comment is added to a review. The problem this helps deal with is teaching new users that when a comment is added to a review, it is not shown to any other users until the review is submitted.

As far as I know, there's currently very little (nothing?) that helps teach users about this concept. Users are expected to just know how it works. I think that some kind of visual indicator when a comment is added to a review would help communicate that further action of submitting the review is required. Something like a pulse is nice because it doesn't require that users read, which few people do.

GitHub's interface both pulses the review button and increments a counter of the number of pending comments in the button's text. I think the counter is nice, but the pulse is a prerequisite since new users may not know to look for the counter.
