Unexpected type checking fail with jsr when mapped type has a named type

[kuuote]

Version: Deno 1.42.1

To Reproduce

Save following code and execute deno check a.ts:

import * as u from "jsr:/@core/[email protected]";

const a = u.isObjectOf({
  a: u.isOptionalOf(u.isUnknown),
});

type A = u.PredicateType<typeof a>;

const aa: A = {}; 

Outputs following error:

error: TS2741 [ERROR]: Property 'a' is missing in type '{}' but required in type '{ a: unknown; }'.
const aa: A = {};
      ~~
    at file:///tmp/a.ts:9:7

    'a' is declared here.
      a: u.isOptionalOf(u.isUnknown),
      ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        at file:///tmp/a.ts:4:3

Note

Same library version from npm passes type cheking.

import * as u from "npm:[email protected]";

const a = u.isObjectOf({
  a: u.isOptionalOf(u.isUnknown),
});

type A = u.PredicateType<typeof a>;

const aa: A = {};

Sorry we missed this one earlier. I have a fix at swc-project/swc#9038
