This is covered in the definition of "definite" in CSS Sizing:

We've clarified it a bit for you by adding an example reference to 2.1:
but basically the answer is that sizes that derive from definite sizes
are by definition definite, and absolutely-positioned elements are
sometimes definite (when they are not shrinkwrapped) and sometimes
indefinite (when they are shrinkwrapped).
