--- Comment #5 from Olivier Fourdan <ofourdan at redhat.com> ---
Yes, as you say, xdg-shell v6 positionner definition makes it clear that the
rectangle should not be 0:

 
https://cgit.freedesktop.org/wayland/wayland-protocols/tree/unstable/xdg-shell/xdg-shell-unstable-v6.xml#n115

      For an xdg_positioner object to be considered complete, it must have a
      non-zero size set by set_size, and a non-zero anchor rectangle set by
      set_anchor_rect. Passing an incomplete xdg_positioner object when
      positioning a surface raises an error.

So the same error occurs with weston as well. 

There is a possibility that we can do, though, if the given size is zero, we
use 1 as with attachment 343383  but then compensate by moving the position by
1 pixel in the opposite direction.

Definitely a hack, but that would give the expected result without breaking the
existing rules.
