Upgrading from v1.2.0 to v1.2.1 results in non-compilable code in _pb.d.ts.

The following (minimized) proto file compiles fine with v1.2.0:

syntax = "proto3";

message Group {
    enum GroupStatus {
        PENDING = 0;
        APPROVED = 1;
    }
    uint64 ID = 1;
    GroupStatus status = 2;
}

The generated code looks like this:

...
  getStatus(): roup.GroupStatus;
  setStatus(value: roup.GroupStatus): Group;
...
export namespace Group {
  export type AsObject = {
    id: number,
    status: roup.GroupStatus,
  }

  export enum GroupStatus { 
    PENDING = 0,
    APPROVED = 1,
  }
}

As can be seen, references to the encapsulated enum type roup.GroupStatus should be Group.GroupStatus. A similar problem happens if the enum type is moved outside the Group message:

export namespace Group {
  export type AsObject = {
    id: number,
    status: roupStatus,
  }
}

export enum GroupStatus { 
  PENDING = 0,
  APPROVED = 1,
}

Command used to compile (works fine with v1.2.0):

% protoc -I=. -I=$(pbpath) \
	--js_out=import_style=commonjs:../$(proto-path)/ \
	--grpc-web_out=import_style=typescript,mode=grpcweb:../$(proto-path)/ ag.proto

This results in compile errors similar to this (included for people searching for this error message):

proto/ag_pb.d.ts:9:16 - error TS2503: Cannot find namespace 'roup'.

9   getStatus(): roup.GroupStatus;
