Using the top slider on that page, try dragging the slider back and forth quickly. Random numbers will pop up at 500ms(?) intervals. When you let go of the slider it will keep updating with random numbers for a long time (I watched it go for 30 seconds).

Not a great workaround, now I can't see the number I'm selecting. With the 500ms render time, it's going to feel really slow to pick a value. The perf needs to be fixed for this to be usable.
