Feature Description

Extending the current scrollable api by adding Scrollbar element.

Problem Statement

I think that current scrollable api confuses dev - it does not provide any explicit visual changes and not provide focusability for elements, that wrapped in it, devs must do the tricks by themselves like empty div element for focus catch (See #145).

Proposed Solution

Scrollbar element is a visual detector of scrollability and the focus marker for elements, that cannot accept @onkeydown because does not have AdditionalAttributes parameter.
