Part of the chart area will not respond to touches

What steps will reproduce the problem?
1. Create any plot, and specify padding on one edge of the chart
2. Enable chart scrolling
3. Touch and scroll at the opposite end of the padded edge. The chart will
not respond to to touch at that point. However, the chart will respond to
the touch and scroll even in the padded area of the chart.

What is the expected output? What do you see instead?
Touching any point inside the chart will allow the chart to scroll.
Likewise, the chart should not respond to any touches outside the chart
area (padded area etc.)

What version of the product are you using? On what operating system?
