Flickering issue when focusing on input at the top of the docs site

[jennyscript-ridecell]

Expected behavior

Component becomes focused and accepts input

Actual behavior

Screen flickers and scroll position changes rapidly. See video.

Steps to reproduce

Load demo page https://reactdatepicker.com/ in Chrome (Tested on OSX Chrome 63.0.3239.132)
Before scrolling or clicking anywhere, click inside the input at the top of the page

Issue also exists on Safari

Also happens on firefox on the demo site

My team experience the same problem, I also found another issue about the same problem #1334

I experienced it in all browsers I had available when testing.

Has the fix been deployed to the https://reactdatepicker.com/ site yet? Because I'm still seeing the behavior in both Chrome and Firefox (but only if my devtools are closed).
