Core: creating ref on projection item with string value overwrites it

[binier]

query().project(q => ({
  myCount: "count(myField)",
  countRef: q.ref('myCount')
}));

outputs:

{
    q1() {
      myCount: v1 as myCount // <- should be: "myCount: v1 as count(myField)"
      countRef: val(v1)
    }
}
