see http://en.wikipedia.org/wiki/Lopatcong_Township,_New_Jersey for an example.
The infobox template expansion generates a lot of paragraphs which result in that space. Probably related to newlines around comments that are stripped by the PHP parser.
To avoid confusion: This is not rt-relevant as those paragraphs are still properly encapsulated. It only affects the appearance of the infobox expansion.
Patch submitted: https://gerrit.wikimedia.org/r/39070
And merged.
