On that test, Safari 5.0.3 on Mac outputs "red" and "transparent" for
the two strings.
And this test:

outputs "red" and "orly, do you think so" in the same browser.
Does Safari on Mac behave differently from Safari on Windows here?

At this point, probably not. If it's not actively breaking websites
it's not being changed before final release. If it is, we'd at least
think about it...
