Your request is reasonable; we should have a way to show a tooltip when the focusTarget is set to 'series'. The only way you could hack this currently is to not use focusTarget set to 'series', but set to 'datum', and handle the hover (via 'onmouseover') and select the series. Here is a demonstration of that idea based on a change of your jsfiddle: http://jsfiddle.net/dlaliberte/yy1ujmau/
I noticed the HTML tooltip was not displaying correctly, which I guess happens if you haven't provided a 'tooltip' role column. Customizing the tooltip will be a bit tedious because you would have to provide a tooltip column after each data column in order to specify the same series summary for every row. Also note that your div sizes were conflicting with your chartArea sizes. I disabled the chartArea sizes.
