System Insight and "Installs" icon textbox

Open Performance > System Insight

System Insight >  graph with "Installs" icons > move the mouse over an "Installs" icon with > 4 installations
a text box comes up, but only 4 installations appear in the box.

 

The textbox has a vertical scrollbar, but you cannot see more than 4 installations!

 

It would be great to see all installations!
