APZ is doing something different from non-APZ here. I don't think it needs to, and I haven't found any problems with the patch I'm about to attach.
Ugh, looks like this is still necessary. I've now found lots of problems with the patch I was about to attach. The main reason is overscrolling: fixed items in the page should be transformed during overscrolling, but elements outside the viewport should not. So they absolutely need to be in different layers.
