Pattern mask does not mask on component mount in React

[dludemann]

Describe the bug
Pattern mask does not mask on component mount in react. Codesandbox was a forked example from another discussion

To Reproduce
Codesandbox

Expected behavior
an input of "20000" should render "$20,000" based on mask. But it renders "20,000".

Mask Used

{
    mask: "$num",
    blocks: {
      num: {
        mask: Number,
        thousandsSeparator: ",",
        radix: ".",
        mapToRadix: ["."],
        scale: 2, // two decimal places
        expose: true,
      },
    },
  }
