Timeline continues to load in more old content every time one scrolls up or down.

Currently with the "Enable automatic loading when scrolled to the bottom" option enabled, the page will continue to load older posts every time I scroll regardless of where I am on the page. This happens regardless of whether I scroll up or down. I have made a quick webm with the option enabled to better show what I meanDesktop_2018.04.21_-_02.05.23.02 Please note the scrollbar as an indicator of it loading more posts.

Currently using google chrome.
