Repro steps:
Put a grid inside a RadBusyIndicator with a button. On a button click, set IsBusy to true, change the height of the grid, and set IsBusy to false. The grid height will not be updated.
Another way to reproduce is to add children views to the grid while IsBusy is true. The children will not be rendered after it's done
This is a regression from a recent Telerik update
