Applying Bitmap Filters to Vector Object

Is this a new feature? Have I stumbled on a bug? This doesn't work in X8 because I still have it installed and I've tried it. I drew a curvy line, colored it, and without converting to a bitmap, I applied Effects: Texture: Plastic. After I do this, on the Object Details it says "Control Curve on Layer 1" and shows line and fill colors. However there is no way I can find to break it apart or separate the vector line from the bitmap effect. Just curious.
