Incorrect completion and navigation with type based disambiguation

[hackwaly]

type a = {
  x: int;
}

type b = {
  x: float;
}

let f (t: a) = 
  t.x (* Here `x` *)

Type (merlin command) at x result int which is correct.
Complete or locate at x shows x belongs b and type of x is float.

Another issue here: Locate at x result a location of type a, not the x field. Is this a feature or a bug?
