While messing about with the content server, I noticed this:
Both ISBN and Chapters are non-taglike composite columns; a taglike composite displays without the gap.
Inspect element shows this for ISBN:
Code:
<tr><td>ISBN:</td><td><iframe sandbox="allow-same-origin allow-popups allow-popups-to-escape-sandbox" seamless="" srcdoc="<!DOCTYPE html><html><head><style>html, body { margin: 0; padding: 0; font-family: sans-serif } p:first-child { margin-top: 0; padding-top: 0; -webkit-margin-before: 0 }html, body { overflow: hidden; color: rgba(57, 50, 43, 255) }</style></head><body><p class="description">9781101208809</p></body></html>" data-last_window_width="1115" style="width: 100%; height: 39px;"></iframe></td></tr>
Where does it get the height of 39px from? p.description is only 18px.
