// When set (for IncrementSlider), it specifies the event that is passed down to trigger
// spotlight events and also doesn't remove the spotlight directional callbacks from the props
// so the Wrapped component can fire them manually or use the callback for the default behavior.

// * aria-valuetext handling
// * use aria-valuetext when set
// * defaults to current value
// * onActivate, set to hint text
// * on value change, reset to value or aria-valuetext
// * Spotlight
// * Pause Spotlight when dragging to prevent spotlight from leaving when pointer enters another
// component
// * Forward directional spotlight events from slider
// * Managing focused state to show/hide tooltip
