LineSeriesGroup: Flickering on resize?

I am trying to create a component of LineSeriesGroup as close as 
possible to the example. I have been getting an effect where, on 
resize, the curves from the original draw are retained (and still 
hoverable). The result is a fractured look.

This does not occur with the example, as built by my same setup. Has 
anyone else seen this? 

Here's where I have made changes: 
The component: 
LineSeriesChart.mxml

The test App (with data): 
ChartTestApp.mxml

This is against 3.4.0.9271, with the currently download-able version 
of Axiis with the bundled degrafa.
