What is use of timeout() in link method in Angular-Kendo wrapper class

We faced an issue on controls painting in IE10 when we have lots of kendo controls in a page( e.g. 10 drop-downs, 5 grids, 10 input fields). While debugging we saw this is happening due to the timeout() in link() in angular-kendo.js. when we commented the timeout. The kendo controls painting is fine. But we are not sure why the timeout is used? Could you please elaborate on the use of timeout() in link(). If we remove the line what could be the impact/issue?
