Nested Grid panel rendering issue (RowExpander)

Hi,

I have requirement to display a Form(contains few fields and grid panel) in a Grid Panel row expander.

Form(contains few input fields) is able to display properly inside grid row expander, but when i add another grid panel inside form, nothing is displayed inside rowexpander. Without grid Form is rendering properly. So i have created example for nested grid. Even nested grid is not rendering.

I simulated the issue in Sencha Fiddle site.

Thanks in advance.
