T51: round 1 fix: on X11 the room above runs to the top of the RandR monitor under her, or of _NET_WORKAREA where that lies lower, since the work area spans every monitor; on Wayland she checks twice a second where the window's size and state put her anchor, counted from the pane as gpui counts it, and opens there again when it moved, since gpui hears a change of state alone as no change of bounds and gives an unseen popup no frames; tiling counts where gpui reports it, for a window it draws itself; her tests move to pet/tests.rs, keeping pet.rs under 500 lines
