 think I was going down this road initially, and the `z-index` was required
 to force the widget to appear behind the panel. But then I went with
 animating the `width` instead, perhaps for parity with the `height`
 animation of the non-wide controls.

 > Oh, I think I may have switched from animating `left` to animating
 `width` to make it easier for RTL. But RTL can be easily accommodated by
 switching `left` to `right` when we detect RTL is on. But to switch back
 to animating position, we'd have to restore the negative `z-index`.

 If we still see the flashing/white in chrome with a lowered z-index with
 the sliding animation, another option would be to raise the z-index of the
 wrapper (maybe .wp-full-overlay-sidebar?) then reset it after the
 animation completes.
