 When adding customizer control with a type of `range`, the preview JS
 doesn't receive an event until the mouse is released.

 I believe the customizer is listening for the onchange event, but it looks
 like that should only be triggered when the user releases the mouse. To
 get continuous updates, you can use the oninput event, which will capture
 live updates in Firefox, Safari and Chrome, both from the mouse and the
 keyboard.

 However, oninput is not supported in IE10, so you might have to combine
 the two event handlers.
