Implicit Root Scroller On Chrome 73

https://www.chromestatus.com/feature/5162094739587072
This update is causing displacement of modals with input fields when the field becomes focused. 
I tested it with this example https://fl3nkey.github.io/scroll-lock/demos/sidebar/sidebar.html on android chrome 75.
Steps to reproduce:
- open modal
- click on the name field
- modal scrolls to the bottom
