Record with t.RegExp preserves unmatching properties

[dodas]

What version of Elysia is running?

1.3.1

What platform is your computer?

Darwin 24.2.0 arm64 arm

What steps can reproduce the bug?

import { Type as t } from "@sinclair/typebox";
import { createMirror } from "exact-mirror";

const schema = t.Record(t.RegExp("^custom[A-Z]"), t.Any());
const mirror = createMirror(schema);

const clean = mirror({ random: true, customProp: true });

What is the expected behavior?

console.log(mirror);
// { customProp: true }

Using typebox's Value.Clean() produces the expected result:

import { Type as t } from "@sinclair/typebox";
import { Value } from "@sinclair/typebox/value";

const schema = t.Record(t.RegExp("^custom[A-Z]"), t.Any());
const clean = Value.Clean(schema, { random: true, customProp: true });

console.log(mirror);
// { customProp: true }

What do you see instead?

console.log(mirror);
// { random: true, customProp: true }
