bug#32207: 26.1; can't set window position with emacs 26.3

This hints at yet another sizing problem.  What happens when you
specify size _and_ position via say

(make-frame '((top . 100) (left . 100) (width . 50) (height . 10)))

Can you try with "Tile Manual Placement" instead of "Tile Cascade"?  I
suppose that Tile Cascade means that the window manager is allowed to
(or even should) override the application's request.

Then maybe

(make-frame '((user-position . t) (top . 100) (left . 100)))

will do?
