Came across this on codepen: https://codepen.io/chasewackerfuss/details/JKGrJJ
Browsed to this on WR Linux and it runs slowly and causes slowness/jank inside of browser chrome in addition to the content area.
Forked the pen at https://codepen.io/anon/pen/PXREaM to ensure it stays up.

This page OOM's on Nightly non-WR,and Chrome
With WR, I can get the page to open and animate. But page uses 1.6-1.7 GB RAM

I take it back - this test is worse on chromium. It gets very slow, then crashes, then crashed my desktop (kde plasma).
