fixedDecimalScale adding zeros to numbers in Input field

### Description of the bug

When having an Input-field using fixedDecimalScale in combination with a prefix it adds zeroes on the wrong side of the decimal-separator, making the number larger than it is supposed to be!


"formatting": {
"number":
{
"decimalScale": 2,
"fixedDecimalScale": true,
"suffix": " kr"
}}

### Steps To Reproduce

1. Create an Input-field for a decimal datafield using formatting decimalScale larger than zero, fixedDecimalScale and a prefix
2. Run and watch as you type...

### Additional Information

_No response_

No file or test is named in the issue. Reproduce the problem with an Input field using decimalScale 2, fixedDecimalScale, and a prefix, then trace the Input-field formatting path. Done means typing the decimal value with the prefix no longer adds zeros on the wrong side of the decimal separator.
