tooltip shows count of servers scaled by PI for a while

Go to the Data Buckets screen, and hover over the circle that shows node health status. When you first load the page, the count will be scaled by PI. For example, if there are 2 healthy servers, it will say "6.281385307... healthy". After being on the page for a little while (a few seconds), the tooltip will start showing the correct count ("2 healthy"). Reload the page, and it will revert to pi-scale for a while.
