[Mayank Bansal]

Go to https://codepen.io/erikterwan/pen/NNNJKY
Click inside the demo-pane and scroll

AR: The memory use increases to 2.5GB+
ER: Probably not so

If you download the demo and run it locally, the memory use is hardly 400MB. Or if you view the demo in full page mode, (https://codepen.io/erikterwan/full/NNNJKY) the memory does not increase more than 400MB.
