title: UiAutomator bug while inspecting WebView elements
body: <p>I have recently started automation testing in android and was using UiAutomator tool for inspecting UI elements. Surprisingly, I came across two different responses for Webview elements for the same screen and same device [Genymotion MotoX 4.4.4]. Attached are the screenshots for the same. We all know that appium has an issue with inspecting webview elements who do not carry "setWebContentsDebuggingEnabled" to true. Is this a bug in UiAutomator?
