ChartPointsBubbleLayer not draws properly

If you run the BubbleExample, I assume changing the useViewsLayer flag should provide the same results, yet its not.

I also having similar issues when tried to implement it with my own example data:

As you can see, the line chart got properly rendered with similar data and similar SwiftChart setup methods.

I guess the ChartPointsBubbleLayer not added to the proper layer. Scrolling and zooming affects the scale below, but not the bubbles.

Using ChartPointsViewsLayer in my project resolves the issues but I am not satisfied with the performance for multiple hundred point views.
