Re: [csswg-drafts] [css-content-3] `content: none` does not work as universally as the spec claims it does. (#12998)

Also https://drafts.csswg.org/css-position-4/#backdrop

> When its computed [content](https://drafts.csswg.org/css-content-3/#propdef-content) value is not [none](https://drafts.csswg.org/css-content-3/#valdef-content-none), [::backdrop](https://drafts.csswg.org/css-position-4/#selectordef-backdrop) pseudo-elements generate boxes as if they were siblings of the root element.
