Issue with .btn-group in td.text-nowrap

Created by: cervengoc

Please check this demo to reproduce the issue: http://www.bootply.com/wWM2a9R8Mt#

The unexpected horizontal overflow seems to be caused by the float: left of the buttons in the btn-group. For me it was unexpected that btn-group contains floating elements. If floating is really needed, it would be good to include the clearfix in btn-groups. It seems like adding the clearfix class to btn-group doesn't solve the issue in itself.

How could I solve this table cell layout issue?

Is there any way to avoid floats in btn-gruops in future versions? I mean for example input-groups are implemented without floats, so btn-groups might have an alternative implmentation too.
