Why use such generic css selector for buttons?

Sorry if I'm missing something, but why is such a generic css selector as .btn-group-xs > .btn, .btn-xs used? This is changing some of our other UI elements which we don't want changed. Could this be changed to use a different selector which only picks up the correct elements for this plugin?

We love this plugin otherwise, so thanks for making it open source 👍

Thanks.
