The application has to react when a given buffer position changes its
position on screen.  If ‘window-text-change-functions’ is sufficient to
determine that (I never used it), it could add itself to that hook and
specify the popup accordingly.  Otherwise, the application would have to
track whether the window was scrolled, resized or moved, or its buffer
modified.  Or, for example, whether an overlay before the popup position
changed from visible to invisible.
