If X is interdependent with Y, it means X and Y are not absolutely independent.
I don't think even realists claim that some things are
absolutely independent. In that case they couldn't even talk about them / couldn't even have a way of knowing that they even exist.
You got a point with your doubts above.
But philosophical realists do insist and claim things out there are absolutely independent of the human mind. Their claim is, external things exist and humans interact with them from the waves emitted which reach the human brain to be perceived and interpreted as real.
The philosophical realist's ace card is this argument;
The moon pre-existed humans and if all human are extinct due to nukes or WMDs, the "moon" will continue to "exists" in the future and thereafter.
This is getting more refine but there are counter arguments to this.
I think what they usually mean is: there is the mind and there is the outer reality, and these two don't interact, don't disturb each other. And yet, thanks to Magic, they are still somehow in the presence of each other.
Yes, they insist there is an absolutely independent external world out there independent of the human mind. Note Moore's proof of an external world.

What they are blind is they don't seem to realize, in the conception of reality, they are part and parcel of that reality which they cannot extricate from to form an
ultimate and absolute independent view.
This assumption was one of the fundamental assumptions of science. That we can remain perfectly objective, we can experiment with the universe without disturbing it. This view was thoroughly destroyed in the last 100 years, science refuted one of its fundamental assumptions (which I find kinda amusing I have to admit). Why this position is called realist is beyond me btw.
That early assumption of independence is applicable to classical Science, e.g. Newtonian which is still necessary and applicable at present.
This is why I mentioned Popper's - scientific theories are at best polished conjectures - and subjected to the relevant assumptions agreed by man.

The issue is controversial; many scientists claim Science [classical] is Philosophical Realism not Philosophical anti-realism. However note the observer's effect, theory of relativity, and Wave Function Collapse where the observers is an integral part of the theory.
Yes and no. These observers aren't the human mind, however the human mind as such an observer is interdependent with the outer reality.
It depends,
Classical Science, independence = yes,
Modern and QM, independence = no.
