+     * should only enable it if they require playback of encrypted video content. It will impose
+     * the following limitations on the WebView:
+     * <ul>
+     * <li> Only one video overlay can be played at a time.
+     * <li> Changes made to position or dimensions of a video element may be propagated to the
+     * corresponding video overlay with a noticeable delay.
+     * <li> The video overlay is not visible to web APIs and as such may not interact with
+     * script or styling. For example, CSS styles applied to the &lt;video&gt; tag may be ignored.
