With Chromium 35.0.1916.153 Debian jessie/sid (274914), there is a black clickable rectangle (<a>) on the left, which is not there in 2014-07-01-03-02-02-mozilla-central-firefox-33.0a1.ru.linux-x86_64.
Per spec, I believe all those <a>s should have auto height, so should be invisible. This is what we implement; this has nothing to do with rowspan, but is true for all the <a>s inside those table cells.
