Protractor: Debug not working in Protractor

I've taken a look through past issues, and to the best of my knowledge, it does not appear to be addressed (these issues appear similar, but all seem to be closed):

• #907
• #552 (Which has further discussion of the problem existing despite being closed)

Version Information:

• Mac 10.9.4
• Node 0.10.30
• Protractor 1.0.0
• Coffeescript 1.7.1

Steps to reproduce:

• Create the following protractor config (e2e.conf.coffee):

    Copied from https://github.com/angular/protractor/blob/master/docs/referenceConf.js
    exports.config =
      seleniumServerJar: null
      seleniumPort: null
      seleniumArgs: []
      chromeOnly: true
      seleniumAddress: null
      sauceUser: null
      sauceKey: null
      sauceSeleniumAddress: null

      specs: ["e2e/*.coffee"]
      exclude: []
      capabilities:
        browserName: "chrome"
        count: 1
        shardTestFiles: false
        maxInstances: 1

      multiCapabilities: []
      maxSessions: -1
      baseUrl: "http://localhost:8081"
      rootElement: "body"
      allScriptsTimeout: 11000
      getPageTimeout: 10000
      framework: "jasmine"

      jasmineNodeOpts:
        isVerbose: true
        showColors: true
        includeStackTrace: true
        defaultTimeoutInterval: 30000

• Create the following spec in e2e/spec.coffee

    describe 'Page', () ->
      it 'should debug properly', () ->
        browser.get '/'

        x = 'There is only X'
        y = 1
        z = ++y
        browser.debugger()

• Run the following command: protractor debug e2e.conf.coffee

Expected Result:

• The break point is set at the correct location
• Variables in the local scope are accessible when entering repl mode and accessing a variable

Results:
Breakpoint is set in timers.js, and can't access any variables in scope other than browser:

protractor debug src/test/e2e.conf.coffee
Using ChromeDriver directly...
Hit SIGUSR1 - starting debugger agent.
debugger listening on port 5858
connecting... ok
break in timers.js:79
  77 }
  78
  79 function listOnTimeout() {
  80   var msecs = this.msecs;
  81   var list = this;
