Steps to reproduce:

I tried to make a parallax style effect in CSS with 3D transforms.

see
https://jsbin.com/seqabutuzu/1/edit?html,css,output
and slowly scroll to the bottom


Actual results:

The element is not being drawn when its original location is out of the window/parent but the projected location is in the window/parent.


Expected results:

The element should have remained visible.
