(I guess this could just be m_layoutListMarker.document(), it should handle the
anonymous nature of the marker. I guess this might be more direct though.)

They are currently always anonymous, so LayoutObject::document() would then
always check m_node and call parent().

Are you fine with keeping this as it is?

Yes.
