I am developing a virtualised grid and I can't rely on the css engine to position the elements for me when the 
scroll area is too big.

Did this work before? No 

Does this work in other browsers? N/A

Chrome version: 64.0.3282.140  Channel: stable
OS Version: 6.1 (Windows 7, Windows Server 2008 R2)
Flash Version: 

In Safari the grid works without glitches, in the console log I can see the numbers don't loose their precision
