Workload Pie Gadget - Can't drill into Other Pie Slice

I am using the Workload Pie Gadget to track my teams remaining effort on a project. The statistic type is "assignee". I can see a pie slice for each of my team members. When one or more of my team members remaining effort drops below 1%, I see that they are consolidated into a single "other" pie slice which is fine. But the problem I have is that I want to click into that pie slice to see who it is and a the gadget is blocking it. Please correct the gadget by allowing me to drill in and see the details in Issue Navigator.
