jdlrobson 6c17af260c Extracts can expand with narrow thumbnails
If a thumbnail is narrow, then the extract can expand to take
the available space. It does this via JavaScript taking the difference
between the normal space for a thumbnail minus the actual space needed
to display the thumbnail.

This removes unused whitespace in both the thumbnail and extract.
