Pivot hide scrollbars if no overflow

Here is an example:

No overflow is happening, so there is no need to display scrollbars. Is there a way to hide them if no overflow is happening?
Thank you.

Hello,

As a solution, you can use Webix CustomScroll (only for Webix Pro edition), which is initialized as:

webix.CustomScroll.init();

The advantage is that the custom bars are initially hidden and appear only when a component is hovered with a mouse pointer and its contents is larger than its size (provided that scrolling is enabled).
