When a reviewer adds maintenance tags to an article via Special:NewPagesFeed (PageTriage extension), a notification is sent to the page author. It contains a link to thank (Thanks extension) the reviewer but the link navigates to Special:Thanks for confirmation. This is problematic because the user loses the context of what they were doing before looking at their notifications.
# Proposed solution
Process the thanks and the confirmation using AJAX without navigating away. This is how it works when thanking from history, diff, or Flow boards.
