WebListBox horizontal scrolling jitters badly

I have a WebListBox that jitters badly when attempting to scroll the contents horizontally with my finger on an Android device. I’ve posted a screen capture showing the problem:

Vertical scrolling seems to be OK. It’s just the Horizontal scrolling that isn’t working smoothly.

A second issue I have with the WebListBox scrollbars is that they are ill suited for touch-screen devices.

It would be great if there was a non-hacky way to make the scrollbars disappear.

Touch-screen users will usually swipe or drag the WebListBox to bring out-of-bounds content into view.

Scrollbars in this use-case are just taking up precious screen real estate.
