Try fast scrolling the page. It will be very janky and uncomfortable.

In general working with large Colabs is very slow.

On Firefox (and Chrome) it is sikly smooth.

Looks like layout thrash (triggered by getBoundingClientRect()) and some expensive layouts.

Page doesn't seem to be using content-visibility.
