Sets or gets the animation triggers for a button's icon.
The only currently supported trigger value is 'hover'. If you set iconAnimationTriggers to an empty array, you can create custom animation triggers using event handlers, such as onClick(). If you don't set iconAnimationTriggers, the button's icon animation is triggered when a site visitor hovers over or clicks the button.
To animate the button's icon in response to a trigger, call animateIconForward() to animate the icon forward, or animateIconBackward() to animate the icon backward.
Note: This property is only supported for buttons with icons in Wix Studio.
