Resolved import has implicit 'any' type without warnings

[jc776]

Describe the bug

To Reproduce

deno.jsonc:

{
  "nodeModulesDir": "none",
  "imports": {
    "react": "npm:react@^19.1.0",
    //"@types/react": "npm:@types/react@^19.1.8"
  }
}

test.ts:

import { useState, aaaaa } from 'react'
import { bbbbb } from 'ccccc'

const x = useState
const y = aaaaa
const z = bbbbb

console.log(x)
console.log(y)
console.log(z)

I set up these files with an npm import, without node_modules dir, but was missing the @types import.

1. Running test.ts correctly shows error for the missing ccccc. This is correctly highlighted red in VSCode (first screenshot).

deno run --allow-env test.ts
error: Relative import path "ccccc" not prefixed with / or ./ or ../ and not in import map from "file:///[omitted]/test.ts"
    at file:///[omitted]/test.ts:2:23

# no error?
deno check test.ts
Check file:///[omitted]/test.ts

2. If I comment out ccccc and z, deno correctly shows an error for the missing import. VSCode does resolve react but does not show the same as an error or a warning. (second screenshot)
   VSCode shows the type of x and y as any. (third screenshot)

deno run --allow-env test.ts
error: Uncaught SyntaxError: The requested module 'react' does not provide an export named 'aaaaa'
import { useState, aaaaa } from 'react'
                   ^

# no error?
deno check test.ts          
Check file:///[omitted]/test.ts

3. If I comment out aaaaa and y, VSCode shows the type of x as any. deno allows this to run, I thought it was set by default to strict and noImplicitAny? What settings do I need to have "no implicit any" enforced on these imports?

deno run --allow-env test.ts
[Function (anonymous)]

# no output?
deno check test.ts

4. If I add @types/react, VSCode correctly shows a red error for aaaaa and shows the types for useState and x. (fifth/sixth screenshots)

Expected behavior

When missing @types/react, VSCode should show a warning or error for the implicit any types imported from react. Currently no error. (third screenshot)

Screenshots

In both cases, the missing ccccc correctly shows error:

Without @types/react, react resolves but no warning or error on aaaaa. x and y have type any with no warning or error. useState and aaaaa just show import aaaaa.

With @types/react, correctly shows error for aaaaa and resolves types for x and useState:
