Definition detection not working for rand variables

[djoffe]

When declaring a class attribute as rand, its definition is not detected:

class foo;
         int unsigned bar1;
    rand int unsigned bar2;

...

    function new(string name = "");
        super.new(name);

        bar1 = 1;
        bar2 = 2;
    endfunction
endclass

Right click on bar1, Peek definition: it works. Right click on bar2, Peek definition: "No definiton found for 'bar2'".
