Failed to import memfs with typechecking

[espindola]

Trying to import

import 'https://esm.sh/[email protected]?target=deno'

with

deno run --check=all --reload  test.ts

fails with

error: TS2300 [ERROR]: Duplicate identifier 'URLSearchParams'.
declare class URLSearchParams {
              ~~~~~~~~~~~~~~~
    at asset:///lib.deno.url.d.ts:8:15

    'URLSearchParams' was also declared here.
            interface URLSearchParams extends _URLSearchParams {}
                      ~~~~~~~~~~~~~~~
        at https://esm.sh/v86/@types/[email protected]/url.d.ts:822:19    and here.
....

This is surprisingly hard to reduce. I downloaded the code with

$ curl -o foo.js -Dheader 'https://esm.sh/[email protected]?target=deno'

and changed the test to

// @deno-types="https://esm.sh/v86/[email protected]/lib/index.d.ts"
import './foo.js'

But this changes the error to

error: Relative import path "querystring" not prefixed with / or ./ or ../
    at https://esm.sh/v86/@types/[email protected]/querystring.d.ts:131:19

The last one at least is easy to see, line 131 has:

 export * from 'querystring';

seems the types is incorrect, you can disable it by ?no-check

Yes, or just not passing --check to deno. I have updated the description to say that the issue is with the .d.ts files, the .js is fine.
