DynamicForm setIsGroup distortion in Chrome

Hi,
Does anybody know what to do with a distortion of a group border when you use DynamicForm.setIsGroup(true) in Google Chrome? I see that the last component is crossed by the bottom line of the group border. I made a screenshot from the SmartGwt Showcase (http://www.smartclient.com/smartgwt/showcase/#form_controls_various)
Please see it in attached files. How to avoid this?

We don't look into bugs in pre-release browsers. This problem is not present in any released version of Chrome.

The same with Safari 5.1.2(7534.52.7). See attachment.

Same here with SmartGWT 3.0 and Chrome 18.0.1025.142 (stable).

Is there a workaround available?

Thanks
