Android : Hide scrollbar - Webview - CrossWalk

How can I hide the scrollbars in the CrossWalk webview?

I've tried the following things:

• 
  

  Applying this to the Webview layout XML

  
  

  android:scrollbars="none"

  
  


• 
  

  Using javascript/css:

  
  

  
  document.body.style.overflow = 'hidden';
  
  



• 
  

  Everything suggested in this SO question: Hiding the scroll bar in WebView

  
  

Any ideas?
