Situation: I was working with the Spark (Flex4) TextArea component. I wanted the background to no longer be visible or just simply alpha set to zero. I expected I could set a stylesheet property backgroundAlpha to zero. However, that didn’t work and there wasn’t even a property on the component called that. I dug in the source to find it and realized it is really contentBackgroundAlpha. Why? I see borderAlpha and expect to follow the same convention! I do not see contentBorderAlpha.

Why break a convention?
Why use contentBackgroundAlpha when borderAlpha is present and there is not already a backgroundAlpha?!
