Prefix/Suffix blocking input when set to a number

[amanda-patterson-ny]

Describe the issue and the actual behavior

In NumericFormat, if the prefix or suffix is set to a number, that number is blocked from being input as the first input.
Ex. If prefix is set to '1', and the user types '1' as their input, nothing is shown. However, if the user types '2' as their input, '12' is shown, which is correct.

Describe the expected behavior

If the prefix is set to '1' and '1' is typed as input, what should be shown is '11'.
