Problem when typing on NumericStepper

[JoseRenan]

Describe the bug
When you try to type a number on NumericStepper, it allows you to type one digit only, to type other digits you have to point the cursor back to the input and finish

To Reproduce

1. Click on the NumericStepper input:
   
2. You start typing, it will input the first digit you typed and then "lock"

Expected behavior

The component should accept the number the user type if it is allowed by the validation rules (min, max etc)

Additional context
This problem is also occurring on the examples on the Styleguide documentation with all the validation props set to their default

Already fixed on #1218
