What steps will reproduce the problem?

1. Create class A, then class B extending A.
2. Implement property getter in A, then override in B
3. Call super.property from B property implementation
4. Run app, all is fine
5. Compile using dart2js, notice internal error

What is the expected output? What do you see instead?
no compile error, a compile error: "internal error: super property read not implemented"

What version of the product are you using? On what operating system?
Version 0.1.0.201205301156, Build 8124
Dart SDK version 8120, Dartium version
Ubuntu

Please provide any additional information below.

class A {
  String get gah() {
    return "merp";
  }
}
class B extends A {
  String get gah() {
    return "${super.gah}ie";
  }
}
