How to prevent scrolling windows with the game libgdx gwt

I export a gwt game from libgdx to Kongregate using the kongregate shell, which creates an iframe and puts the game into it. Looking around, I found out about tidbits on how to put window.focus () to let the game really pick up the keyboard, but when I use the arrow keys, it scrolls the actual browser window and also makes it very annoying.

Is there a way to ignore the browser when the iframe is in focus to avoid this?

thanks
