title: Does Android 4.4 webview support CSS mask?
body: <p>On Android 4.4 <em>(KitKat)</em>, is there any reported bug regarding <strong>-webkit-mask</strong>?<br>
  in <strong>Chrome</strong> <em>(Nexus 10)</em>, the mask render <strong>perfect</strong>, <br>but in a <strong>Webview</strong> <em>(Same tablet)</em>, the mask render a <strong>black shape</strong> instead.<br><br>
  I thought that the CSS render in Chrome and Webview were the same since KitKat?<br>
  I have searched alot, but didn't found anything about CSS differences between both.<br>
  Anyone have an idea or a link that can help?<br><br>
  Thanks</p>
