Watchlist was made functional on non-JS browsers on mobile in T196893.
When a user wants to remove a page from the watchlist using a javascript-disabled browser, he could do that using the same method as adding the page to the watchlist. But contradictingly the page that is shown after a successful removal has the watchstar filled indicating the page is still in the user's watchlist (but it isn't). This should be corrected.

= Developer notes
I've definitely seen this issue before (in Vector) and it's a race condition/caching problem and not specific to Minerva. I cannot replicate this right now...
