- User B watches a talk page of which the title contains an ampersand. For example "Talk:Mission & Values", or this sandbox test case on mediawiki.org/wiki/Talk:Structured Discussions/Sandbox & Box of sand. Simply view the board and ensure the Watchstar is on.
- User A creates a new topic on this board. E.g. new topic "Foo"
- Another topic is created, e.g. "Bar" either by a third user or the same user A, doesn't matter.
Observe User B browsing the wiki, any page is fine except the talk page in question, and it has a new notification, which when viewed is as follows.
Actual result
It says Stop watching new activity on "Sandbox & Box of sand"
Expected result
It should say Sandbox & Box of sand instead of Sandbox & Box of sand.
Other Info
I initially did not know how to reproduce it after seeing it once. I have confirmed that the notication for a reply to a watched topic is fine, and that the first notification for a single new topic on a watched talk page is also fine. It is only after the first one that the issue appears.
