Subject: [PATCH] Fix top keyline on tables with hidden col headings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The way that we collapse column headings so that they don’t take up any
vertical space is by setting their `font-size` to zero. However this
seems to take them out of the flow of the document, so their top border
also disappears. This commit sets the `font-size` to the smallest
non-zero value to avoid this.
