Tracks appear multiple times when scrolling in Safari 11.0.2

Cool project.
Steps to reproduce:

1. Sign in
2. There is only one track from someone I follow
   
3. If I scroll, the track appears a few more times. This step can repeat endlessly.

Didn't know about it. Maybe a Safari user could pick this up! :)
