Intercept that filters numbers seems to be letting '.' onto a React form input

I have a:
2. [X ] Issue:

Here's my sample code: https://codesandbox.io/s/G5v71oDA8

I have an intercept that will only allow numbers to be added to model.age. I'm not sure how, but I'm able to add a . onto the input. It will not hit the model, but it will show in the input. If I type another . the first will be removed.

Wow! I searched for this, but no way I was going to find it. Thanks @urugator!
