@vmpstr and I did some investigation together today on the sticky demo. Our findings:

With the "divs" version, changing to and from the compact mode was about 120ms on my beefy Linux box. With virtual-scrollers, it was about 20ms. Better, but still not so great. We suspect that this may be slowed down by needing to do self-rendering (style, layout, etc) on all of the locked roots.

Next up would be to compare against a version that has display:none rather than lock for things offscreen to compare.

This seems like it'd be best on the Chromium repo, as it won't impact the spec or demo? (I already find it a bit troublesome to do the demo development in the explainer/spec repo, but ah well.)

I think it is very active (as it is now) it's weird. Maybe best to split of the repos?

Let's close this and reopen in fergald/virtual-scroller-demos or the Chromium bug tracker as necessary.
