In this snippet,
the PHP parser + Tidy combo doesn't wrap the image in a p-tag. Parsoid wraps it in a p-tag. This then introduces a small whitespace rendering diff in the infobox -- this might be the source of several of the visual diffs seen in infoboxes where there is a leading image.
This could potentially also go away when Tidy goes away. Might not be worth fixing right yet.
