Enum properties are capitalized in JS files

[dasois]

The proto file

syntax = "proto3";
package testEnum;

enum Test{
	Prop1 = 0;
	PROP2 = 1;
}

compiles to the d.ts file

import * as jspb from "google-protobuf"

export enum Test { 
  Prop1 = 0,
  PROP2 = 1,
}

together with the js file

/**
 * @fileoverview
 * @enhanceable
 * @suppress {messageConventions} JS Compiler reports an error if a variable or
 *     field starts with 'MSG_' and isn't a translatable message.
 * @public
 */
// GENERATED CODE -- DO NOT EDIT!

var jspb = require('google-protobuf');
var goog = jspb;
var global = Function('return this')();

goog.exportSymbol('proto.testEnum.Test', null, global);
/**
 * @enum {number}
 */
proto.testEnum.Test = {
  PROP1: 0,
  PROP2: 1
};

goog.object.extend(exports, proto.testEnum);

Trying to access Prop1 therefore leads to run-time errors.

You can avoid the problem by following the all caps style for enums, as outlined in the style guide for Protocol Buffers, but the system should behave differently when the style is not followed instead of just silently breaking.

Should be fixed now.
