Toggling the "animate" option will pause an animating slideshow, but will not start animation for a paused slideshow

In order to add an accessibility requirement for a play/pause button, I tried changing the state of the "animate" option. This works to turn off the animation, but will not allow you to turn it on by changing "animate" to true.
