I'm using the the google.visualization.DataTable to display an orgchart and I want to highlight parts of the tooltip via html. Is this possible?

Note that I can get the title to display as html, but I cannot get the tooltip to display as html.

As an example, I get this result:

With this code:

<html>
  <head>
    <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
    <script type="text/javascript">
      google.charts.load('current', {packages:["orgchart"]});
      google.charts.setOnLoadCallback(drawChart);

      function drawChart() {
        var data = new google.visualization.DataTable();
        data.addColumn('string', 'Name');
        data.addColumn('string', 'Manager');
        data.addColumn({ type: 'string', role: 'tooltip', 'p': { 'html': true, 'role': 'tooltip' } });

        // For each orgchart box, provide the name, manager, and tooltip to show.
        data.addRows([
          [{v:'Mike', f:'Mike<div style="color:red; font-style:italic">President</div>'},
           '', '<div style="color:green;">The President</div>'],
          [{v:'Jim', f:'Jim<div style="color:red; font-style:italic">Vice President</div>'},
           'Mike', 'VP'],
          ['Alice', 'Mike', ''],
          ['Bob', 'Jim', 'Bob Sponge'],
          ['Carol', 'Bob', '']
        ]);

        // Create the chart.
        var chart = new google.visualization.OrgChart(document.getElementById('chart_div'));

        // Set chart settings.
        var options = {
        allowHtml:true,
        isHtml:true,
        tooltip:{isHtml:true},
        }
        // Draw the chart, setting the allowHtml option to true for the tooltips.
        chart.draw(data, options );
      }
   </script>
    </head>
  <body>
    <div id="chart_div"></div>
  </body>
</html>

Thank you.
