I tried to reproduce the reported behavior but to no avail - please, refer the video from my test here
. I made the test with the mentioned by you version of the controls (2013.2.611.40) in the latest version of Firefox, Chrome and IE9, 8 and 7. Could you verify that there are not any global CSS styles added to your project (using tag selectors)? If so, can you disable them and see whether the problem still occurs?
If this does not help in solving the case - could you isolate the issue into a sample fully runnable project
and send it so we could investigate it further?
