Hello Telerik team.

We found a problem tabstrip control.
we are using telerik version 2012.2.912.40

I created approximately 15 ~ 20 tabs, click tabstript's scroll button for moving end of right side.
and click the close button while tab count is 0.
sometimes tabcontrol is invisible or cut the left side tab area.

I implemented some codes for reproducing problem at radtabstrip control.
here is my code and screenshots
