The universal setting in the boostrap.min.css file that was causing the issue is presented as follows:
*, *:before, *:after {
box-sizing: border box;
}
Two resolve the issue, I simply updated the CSS element associated with the controls that were being "squashed" as follows:
#mcc-search-bar * {
box-sizing: content-box;
}
Once in place, the controls that were leveraging the mcc-search-bar class now appeared as expected.
