/**
 * @summary Copy buttons copy text to the clipboard when the user activates them. They provide built-in success and
 *  error feedback so users know the copy worked.
 * @documentation https://webawesome.com/docs/components/copy
 * @status stable
 * @since 3.6
 *
 * @dependency wa-icon
 * @dependency wa-tooltip
 *
 * @event wa-copy - Emitted when the data has been copied.
 * @event wa-error - Emitted when the data could not be copied.
 *
 * @slot - The trigger element. By default, a copy icon button is rendered so this is optional. If desired, you can slot
 *  in a custom element such as `<wa-button>` or `<button>`.
 * @slot copy-icon - The icon to show in the default copy state. Works best with `<wa-icon>`.
 * @slot success-icon - The icon to show when the content is copied. Works best with `<wa-icon>`.
 * @slot error-icon - The icon to show when a copy error occurs. Works best with `<wa-icon>`.
 *
 * @cssstate success - Applied when the copy operation succeeds.
 * @cssstate error - Applied when the copy operation fails.
 *
 * @csspart button - The internal `<button>` element.
 * @csspart copy-icon - The container that holds the copy icon.
 * @csspart success-icon - The container that holds the success icon.
 * @csspart error-icon - The container that holds the error icon.
 * @csspart feedback - The internal `<wa-tooltip>` element.
