_experimentalVirtualization glitchy

We enabled _experimentalVirtualization and see some glitchyness when scrolling. See video.

Hey @mkilpatrick! Thanks for reporting this.

We're also tracking follow ups to virtualization in #1623.

Quick question for you, are you able to reproduce this in the demo?
Are you doing some specific styling in your components or customization of the overlay?

I'm having a hard time replicating this in the demo, and I wonder if it could be environmental.

Just add I was able to reproduce this during initial development but thought I had fixed it. I think it's possible to reproduce with the demo.

We can't easily make a reproduction, but it appears to be related to rendering images. When it starts glitching out the images are being downloaded in the network requests constantly. It might have something to do with the image rendering with no width and height and then popping into place, which messes with the virtualization and it gets stuck in a loop.

The issue does appear to be related to images. I was able to reproduce this in the demo by adding lots of Logos sections to the page and scrolling around.
