Add divider line in between city / county / state/province / nation chunks of data in pop up info window box

Screenshot of info window box when searching "san francisco" - can we add a grey line in between each chunk of information to visually divide them? So it would say "view associated resource" + some white space for a line break, and then have the divider line in between each chunk. Note the current site does not do this, so it is more of an enhancement, but would help categorize the info more clearly.
