Hi, I'm trying to use a custom parser for the value type of a record, but it looks like the original value is being included in the output instead of the parsed value. This is causing typing issues, as the parser is interpreted correctly by TS, but the actual parsed value does not match.

import * as r from "runtypes";

const schema = r.Record(
	r.String,
	r.Array(r.String).withParser((arr) => new Set(arr)),
);

const parsed = schema.parse({
	key: ['value1', 'value2']
})

console.log(parsed.key?.constructor.name); // logs Array
