This is not the right place. The event will not bubble up if you do this here.
This code should be after line 509. Instead of using GetEventHandlerForPoint in
the loop, it will use GetEventHandlerForRect

Done.

You could perhaps use bounding_box.set_origin here instead of creating
touch_rect

Done.
