Flash - TextFlow Object - Embedded Font Not Working

I have embedded a Font in my flex app. That works on any components without problems.
@font-face {
src:url("../assets/fonts/wedtxtn.ttf");
fontFamily: "CSSFont";
cff: true;
}

However, when I try to apply the font to my TextFlow object, it is not working. However, it does work when I use the FTE and do it my self. I debugged through the TLF and the looks like the correct FontDescription is created.

Here is the code I use to create text (Full Source @ Pastbin)
var element:SpriteVisualElement = new SpriteVisualElement;
element.verticalCenter = 0;
element.horizontalCenter = 0;
// Create Text using TLF
var span:SpanElement = new SpanElement();
[Code] .....
