Clicking on buttons with Chrome 45 and mobileEmulation fails

[GoogleCodeExporter]

Issue Description:

Clicking on a button when using Chrome 45 (canary) and mobileEmulation is 
causing the click to register on the wrong element. A complete example is here: 
https://github.com/juliemr/webdriver-bugs/blob/master/mobileclick.js

The test attempts to click on 
driver.findElement(webdriver.By.id('thebutton'));, but the click is actually 
intercepted by a number input on the page.

This only occurs when using Chrome 45, and when using mobileEmulation in the 
chromeOptions (as shown in the link above):

  'deviceMetrics': {
    'width': 600,
    'height': 960,
    'pixelRatio': 2
  }

I am using selenium standalone 2.46.0, ChromeDriver 2.16, and 
selenium-webdriver node.js module 246.0.

The output from selenium is:

Issue is reproducible:- this issue is reproducible with ChromeDriver 2.16 but 
NOT reproducible with ChromeDriver2.15.

Also:-

Reproducible when running chrome as node using Grid:- WebDriver driver = new 
RemoteWebDriver(new URL("http://localhost:4444/wd/hub"), capabilities);

It works fine when using normal instance :-  
ChromeDriver driver = new ChromeDriver(capabilities);

untriaging the issue for now.

Issue is also reproducible on Mac platform, with chromedriver 2.16 and chrome 
canary 45

And there is a strange behavior on Linux, it works fine with 2.16 but fails for 
older version 2.15 on Chrome 45.0.2427.7 (Official Build) dev (64-bit)
