thanks for bringing up this issue. This is indeed a silly bug in the
window layouter. I just fixed it in [1].

This is not possible out of the box. One idea to achieve that would be
adding 'width' and 'height' attributes to the layouter's policy,
following the pattern of 'xpos' and 'ypos'. But instead of immediately
setting the window to the specified size, the layouter would set the
'requested_size' of the window. Internally, this would be handled like
if user manually attempted to drag the border of the window to the
specified size. The actual size will be set only if the application
actually responds to the resize request. This is just an idea. I have
not tried this out.
