layout: Do not inherit node and fragment flags in anonymous boxes (#31586)

Browse source 
This doesn't really have observable behavior right now, as much as I
tried to trigger some kind of bug. On the other hand, it's just wrong
and is very obvious when you dump the Fragment tree. If you create a
`display: table-cell` that is a child of the `<body>` all parts of the
anonymous table are flagged as if they are the `<body>` element.
