ChromeVox: sprited images are altered navigating through the page

What steps will reproduce the problem?
1. Create a test html page with the following html (image taken from Office 
365):

<html>
    <head></head>
    <body>
        <div>
            <a href = "#">
                <div>
                    test goes here
                    <br/>
                    <span style = "width:16px;height:16px;position:relative;overflow:hidden;display:inline-block">
                        <img src = "https://ppe.msocdn.com/3.06.4315.1/Chrome/en-US/webcontrols.png" style = "border-width:0px;top:-163px;left:-315px;position:absolute;width:auto;height:auto"/>
                        <br/>
                        test goes here
                    </span>
                </div>
            </a>
        </div>
    </body>
</html>

2. Now navigate over the anchor element using ChromeVox Navigation
3. Notice the image now is positioned differently than before

What is the expected output? What do you see instead?
That sprited images are maintained when using ChromeVox navigation.

What version of the product are you using? On what operating system?
ChromeVox 1.27.0
Chrome 28.0.1500.72 m
Windows 8 64bit
