Exporting one artboard of many to SVG wrote the whole document's art into
that artboard's file, the other artboards' art outside its viewBox: an
editor opening it showed every artboard's art. A file for an artboard
named in the export (Use Artboards with a range or All, Export for
Screens) now holds the objects over that artboard only, at any depth of
layers, as DXF's crop leaves them; objects reaching into it stay whole
and a clipping layer keeps all of its objects. An SVG with no artboard
named (Save As) still holds the whole document.
Part of #546: Export As with a range writes the chosen artboard alone in
SVG, DXF, PDF and PNG, each file with that artboard's art (tested from
the dialogs).
