Indeed.  I probably tried to optimize it before pushing.  Should be
fixed now.

I see.

The problem is rather that 'display-buffer' wasn't used in the first
place to show the buffer.  Two things we could try to cover buffers that
are shown via 'set-window-buffer' are

- Invent a new buffer-local variable, say 'inhibit-temp-buffer-resize'
  with the obvious meaning.

- Invent a new window parameter 'inhibit-temp-buffer-resize' with the
  obvious meaning.
