Docs pages constantly consume 30% CPU when right sidebar is showing

[russelldavis]

Seems to happen on any page, e.g.: https://orm.drizzle.team/docs/overview

In Chrome, it eats 30% CPU. In Safari, it's about 16%. In Firefox it's fine.

While looking for any obvious causes, I noticed that if I resize the window so that the right sidebar disappears, the problem goes away. Maybe an issue with the ads? Although it seems to happen with and without uBlock Origin enabled.

I'm using a Macbook Pro M1 on Sonoma.
