Highcharts- Tooltip HTML max width

I am having some trouble getting the Tooltip for a series to not exceed a fixed width. I would like to tooltip for the Notes to not exceed a certain width, but I don't want it to be a fixed width. Here is a jsfiddle example. http://jsfiddle.net/mnucci/hsBSV/ If you mouse over the second note at the top, it will be way too wide. I am also having a problem getting the tooltip to honor the useHTML flag or the Formatter function. I also tried using a style setting like ``` .highcharts-tooltip span { width:140px; overflow:auto; white-space:normal !important; } ``` but this fixed the width to 140 even when there were only 10 chars and I don't want all tooltips to inherit this, only the note series.
