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

> Otherwise you have layout cycles (since the fixed pos hypothetical position depends on the top layer being already laid out, but the top layer could be in a regular fixed pos too).

I don't see how the top layer can "be in a regular fixed pos". If an element has an ancestor that is position:fixed, then while the element is in the top layer, that position:fixed element does not affect the element's layout. The top layer reparents the element in the layout tree.
