RTF Question: Is this a bug or by design?

In Vista, customize your visual Theme to use a "classic appearance" and
select "High Contrast Black".
Open WordPad (which uses an RTF Control/View). Type some text and print it.

You'll see the text gets printed, inheriting your visual style white text on
a black background.

Set the same Visual Theme in Windows XP and open WordPad, type some text and
print it.
You get Black Text on a white background.

The behavior in XP is what I would expect. I have a bug in our application
because of the behavior we see in Vista.

I don't want to try to report this as a bug to MS though if you all feel the
behavior I'm seeing isn't a bug, but by design.

Thoughts?
