> The two CBs explanation "imposes" a layout order, is that layout order well defined for fixed-inside-abspos and so on?

I think so? This shouldn't be any different to something like:

```
<!DOCTYPE html>
<div style="contain: layout;"> <!-- forced containing block -->
  <div style="position: absolute;"></div>
  <div style="position: fixed;">
    <div style="position: absolute;"></div>
  </div>
</div>
```
