Kengo UI Grid doesn't work correctly with ng-show

Hello.

Here is the example of wrong behavior - http://dojo.telerik.com/@paul/eWemi :

1. click 'Run' and right after that click 'Show Grid' - grid will be loaded with correct height;

2. click 'Run', wait 3-5 seconds and then click 'Show Grid' - data will be loaded on top of grid's layout;

Do you know how to fix it or any workarounds?

Thank you.

Paul
