Chrome Version: 60.0.3112.113 (Official Build) (64-bit)
OS: Windows + Mac, presumably all desktop

What steps will reproduce the problem?
(1) Visit a foreign language video on YouTube
(2) Trigger translate from the right-click menu
(3) Use search or sidebar to navigate to other videos

What is the expected result?
Regular behavior: each video is played with title + comments translated

What happens instead?
After navigation, the title of the video isn't replaced, and each video's like / dislike / subscribe info is appended instead of replaced
