[email protected] This issue comes from the commit 83824fa

    /**
     * Returns the support of the given action, or all actions if no action is
     * given.
     * @param {String} [action]
     */
    static isSupported(action = ['copy', 'cut']) {
        const actions = (typeof action === 'string') ? [action] : action;
        let support = !document.queryCommandSupported;
        // document.queryCommandSupported is a function, so support is always false ?
        actions.forEach((action) => {
            support = support && !document.queryCommandSupported(action);
        });

        return support;
    }

Must be

    /**
     * Returns the support of the given action, or all actions if no action is
     * given.
     * @param {String} [action]
     */
    static isSupported(action = ['copy', 'cut']) {
        const actions = (typeof action === 'string') ? [action] : action;
        let support = !!document.queryCommandSupported;

        actions.forEach((action) => {
            support = support && !!document.queryCommandSupported(action);
        });

        return support;
    }
