[csswg-drafts] [css-position-3] Containing block of dialog fixed position children (#8040)

rwlbuis has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-position-3] Containing block of dialog fixed position children ==
I wonder what the cb should be of the fixed positioned dialog child:

<html>
....
<div>
  <dialog> <!-- in top layer -->
    <div style="position:fixed">
....

If this test is valid then the  fixed positioned dialog child'cb is html aka viweport:
 https://wpt.fyi/results/html/semantics/interactive-elements/the-dialog-element/top-layer-stacking.html?label=experimental&label=master&aligned

I have heard some opinions though that the dialog itself should be the cb.

I can't really conclude from the spec what the cb should be, for one thing what should qualify something to be a fixed positioning containing block seems not specified in one location/spec. Is there something I am missing in the spec and/or what do people think should be the cb in the example?
