copy filter called twice

Hi,

Copy filter function called twice for same source and destination. I found a similar report for emptyDir, but couldn't see a case for copy.

Is this expected for some reason?

Example:

// Below code outputs: 1 2, whereas I expected only 1.
const { copy } = require("fs-extra");

let i = 1;

copy("README.md", "README2.md", {
  filter: () => {
    console.log(i++);
    return true;
  },
});
