When a reviewer selects text to comment on an article before a review session has been started, no indication appears explaining why the comment option isn’t available, which can make the action feel unresponsive.

Show an inline prompt or tooltip when a reviewer selects text without an active review session, directing them to the Start review control to enable commenting.

Benefit: Reviewers get immediate, clear feedback in the moment and can begin commenting more quickly, without needing to guess why the comment option isn’t appearing.
