On iPad, Scrolling gets stuck. There is sometimes no momentum. Sometimes I can’t scroll the page at on. It seems all right on iPhone.

I feel like the experience is worse using the trackpad accessory with the iPad, but it’s plenty bad with just finger scrolling.

The page scrolls mostly fine for me. At one point I got an overlay; if you have a content blocker that hides this, it may still result in blocked scrolling.

There is a period where pages tiles stop painting, which looks like a busy main web content thread.

There's a perdiod of about 1.5s where the page finishes an XHR and spends all that time running script.

I no longer can reproduce this.
