Using the position of point of the current buffer when WINDOW is
specified doesn't make any sense.  Moreover the Elisp manual says that

  "The argument POSITION defaults to the current position of point in
  WINDOW"

which doesn't make sense if point is taken from a buffer not shown in
WINDOW.  So the fix should be implemented in Fpos_visible_in_window_p.

> it should get position from the selected window's buffer?

I don't understand this last sentence though.
