It does, but I think that only fixed part of the issue. With
GDK_BACKEND=x11, I get the right results, but with the Wayland backend
I always get "(26 . 23)" wherever I place the frame(although if I
maximize the frame I get "(0 . 0)"

This might be an effect of the Wayland coordinate system insanity that
they've foisted on the rest of the world.
