/**
 * A button for toggling the fullscreen mode of the player.
 *
 * 💡 The following attributes are updated for your styling needs:
 *
 * - `media-can-play`: Applied when media can begin playback.
 * - `media-fullscreen`: Applied when the media has entered fullscreen.
 *
 * 🚨 The `hidden` attribute will be present on this element in the event fullscreen cannot be
 * requested (no support). There are default styles for this by setting the `display` property to
 * `none`. Important to be aware of this and update it according to your needs.
