Discussion menu flickers when scrolling in mobile browsers

Description

When a user accesses the discussion forum (example) on a mobile device, the posts and menus jump when the user scrolls down.

This was reported by MITx, but is impacting all courses. I was able to reproduce on iOS and Android, in both mobile Safari and Chrome. An MITx course team member was also able to reproduce with a narrow browser window on a desktop, and sent us a screen recording of the error.
