Tapping button very quickly can advance intro multiple steps

[EnduringBeta]

This is a very minor issue, but I notice it when I'm testing on my computer. I can double-click on a button, and it will move from step 1 to step 3. I'm not sure if anyone taps that fast, but it seems possible.

I am using custom overlay/button. I haven't tested the default to see if that also has this issue.
