If the author wants the focus ring to be drawn on objects that are 
clicked on the canvas, then I believe the script would be able to call 
element.focus() on the corresponding element, which would trigger the 
onfocus event, which could then repaint the canvas with an appropriate 
focus ring.  So it is possible to do what you're saying, but it does 
require the script author to take the appropriate steps to achieve it.
