Partial inline item builder (where we turn the tree structure into a flat one) is supposed to initialize the layout queue all
the way up to the damaged box, so that the actual "building" loop can start building the inline items right at the damaged content.

Let's move to a simple, recursive approach as we don't need to process individual layout boxes here.
