I can also reproduce - the "showing results for [x]" link doesn't cause a navigation and update the title. 

looks like it's reported internally as 78181487

Since it's a server-side issue, closing this, but thank you for the report! If it's fixed server side it'll be fixed for all client Chrome versions simultaneously.
