// The popover for the footnote. This popover will be, by default, be sized and positioned
// by the script. However, many of the sizes can be established in this stylesheet and
// will be respected by the script. `max-width` will limit the width of the popover
// relative to the viewport. `width` (on `bigfoot-footnote__wrapper`) will set the
// absolute max width. Max height can be set via a `max-height` property
// on `bigfoot-footnote__content`.
// By default, the popover has a light gray background, a shadow for some depth,
// rounded corners, and a tooltip pointing to the footnote button.
// @state .is-active - The popover has been activated and is visible.
// @state .is-positioned-top - The popover is above the button.
// @state .is-positioned-bottom - The popover is below the button.
// @state .is-scrollable - The popover content is greater than the popover height.
// @state .is-fully-scrolled - The popover content is scrolled to the bottom.
// @since 2.1.0
