SauceLabs config not working or documentation incorrect

[muteor]

On the SauceLabs documentation page (http://datasift.github.io/storyplayer/devices/saucelabs.html) it shows the config required for using saucelabs is:

{
    "environments": {
        "defaults": {
            "saucelabs": {
                "username": "<saucelabs-username>",
                "accesskey": "<saucelabs-accesskey>"
            }
        }
    }
}

However doing this results in exception in DataSift\Stone\ObjectLib\BaseObject for No such property: saucelabs on instance of class.

Tracing it back the storyTeller object inits the device from the $staticConfig and seems to make no attempt to merge in the saucelabs section in. As a workaround this does work:

"devices": {
        "sl_ie9_win7": {
            "saucelabs": {
                "username": "<saucelabs-username>",
                "accesskey": "<saucelabs-accesskey>"
            }
        }
    }

But I am having to repeat the config per device this way.
