Details

(Whiteboard: [platform-rel-facebook]) 

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:55.0) Gecko/20100101 Firefox/55.0
Build ID: 20170605030204

Steps to reproduce:

Sign into facebook.
Scroll up and down timeline quickly


Actual results:

The content in the middle panel vanishes until scroll completes


Expected results:

The content is visible while it scrolls.

Note that this isn't an issue of the page downloading data async. Scroll down slowly to show that content is there, then scroll back up quickly and watch as the entire middle column of the app vanishes.
