Overlapping Flare canvas in Flex, how to clip it to the container?

Question

I'm having a serious issue when trying to display a FlareCanvas within my application. It simply doesn't respect the bounds (see image here)

I've tried "clipContent" and a bunch of alternatives but nothing seems to prevent the canvas of being "passing" over its container. What should I do? It is taking me several weeks!

In Flex main.mxml:

<flexvis:FlareCanvas id="graph" width="800" height="600" verticalScrollPolicy="on" clipContent="true" horizontalScrollPolicy="on"  />

The full class FlareCanvas which FCACanvas extends is in: https://github.com/prefuse/Flare/blob/master/flare/src-flex-integration/flare/flex/vis/FlareCanvas.as
