[VM] Possibly incorrect error message when explicitly using this in a constructor initializer

Code:
class C {
  C() : v = this.f {}
  var v;
  final f = 1;
}

The compile-time error I see on VM is:

unexpected use of 'this' in primary expression
  C() : v = this.f {}
            ^
According to spec, the initializer requires a conditionalExpression argument, which can be reduced to a postfixExpression of the form primary.identifier and this.f perfectly matches this production.
When an unqualified invocation/field access is used, the error is about illegal access to 'this', and it should probably be the same error in this case.

If I understand this right, the request is to have the same error message whether I write v = f or v = this.f in the initializer. That makes sense, will do.
