Hello, just trying the new css system color keywords. Just found that on Safari 16.4, the `AccentColor` is always blue, and doesn't reflect the system accent color.

Reproduction:

I would expect the css color AccentColor keyword to reflect system changes.

This is currently intentional behavior as a fingerprinting mitigation, to avoid exposing additional user preferences to websites.

Ok, i understand that. But the color does't change at all even after page refresh. The AccentColor keyword is supposed to reflect the system accent color (per spec), while currently it stays blue no matter what.
