As a Watchlist Expiry user, I want the Timeless skin to show the half star when a page is being watched temporarily, so I can easily determine the watch status of a page by viewing the star.
Background
Currently, the Timeless skin only has the "full" watchlist star.
I am guessing we need to do the same thing we did for Vector in T248495.
Acceptance Criteria
- Display half star when page is being watched temporarily on Timeless
