On the autopilot helpers, the swipe to delete a list item assumes the window is on the top-left

[Leo Arias]

There's an autopilot helper to drag a list item from left to right to delete it.
It assumes that the window is on the top-left corner of the screen, so it just uses the width as the starting point:

self.pointing_device.drag(w - (w*0.1), ty, x, ty)

This fails if the window is on a different place, because instead of just using the width, we need to take into account the x of the window.
