IE Bug with Buffered Grid in Tab Panel

Hi All,

I am facing an issue with the Buffered grid in a tabpanel ( specific to IE ).

Descripotion :

This sample works perfectly on Chrome browser. But when we run this browser on IE 8/9 we can find a bug.

Bug :

In the first tab scroll the grid, And then revisit the First tab from Second tab.( after scroll activate the second tab and come back to first tab again) The First tab will be empty untill you click or scroll on the empty area. This issue exists with below combination

Buffered Grid,IE,TabPanel

I have prepared a POC which can reproduce the issue.

To Preview using below link. As my sample uses sencha form api for data, Which is not working in fiddle ( not sure about the reason ) but it works on preview.

Any Help is Highly appreciated.

Observation : When i revisit to the first tab again, empty area is shown and when i mouse down on that empty area the grid view is visible with the preserved scroll bar. I have verified the html elements of the gridview,grid container and row. No styles appared to me which is hiding the records. Records elements actually exists but not visible.
