I understand only partially but probably we see the same.  When I drag
the right internal border here it disappears.  When I now drag the
bottom border, the right border reappears at its old position, making
the previous drag a noop, and the bottom border disappears.  So in
practice I cannot move any border.

Do you mean that with an earlier patch you could arbitrarily move those
borders (using an insanely large initial child frame)?  If so, please
tell me which patch that was.

Here nothing happens in this regard.

Probably so.  I tried to translate from my locale.
