     * trigger, but that might not be desirable on particular elements (e.g. inputs and draggable
     * elements). The different values for this option configure the touch event handling as follows:
     * - `auto` - Enables touch gestures for all elements, but tries to avoid conflicts with native
     *   browser gestures on particular elements. In particular, it allows text selection on inputs
     *   and textareas, and preserves the native browser dragging on elements marked as `draggable`.
     * - `on` - Enables touch gestures for all elements and disables native
     *   browser gestures with no exceptions.
     * - `off` - Disables touch gestures. Note that this will prevent the tooltip from
     *   showing on touch devices.
