Re: [csswg-drafts] [css-display] Becoming a formatting context without display types

https://drafts.csswg.org/css-contain/#containment-layout : 
> If the element does not generate a principal box (as is the case with `display: contents` or `display: none`) [...] layout containment has no effect.

In other word, "becoming a formatting context" is not invoked by the contain property on `display: contents` elements. So from the point of view of that spec at least, it does not matter what the definition of "becoming a formatting context" is for that case.
