I need to have vertical scroll bar for the viewport, but not horizontal scroll bar.
Inside viewport, I have a panel and need to have horizontal scroll bar but not vertical scroll bar.

I tried:
autoScroll: 'y' for viewport, autoScroll: 'x' for panel.

But still it seems that both are treated as autoScroll: 'true' (verical and horizontal scroll bars appear for both viewport and panel).

Thanks.
