tsc --watch doesn't pick up on changes to --jsx

[DanielRosenwasser]

// ./tsconfig.json
{
    "compilerOptions": {
        "target": "esnext",
        "module": "commonjs",
        "noEmit": true,
    }
}

// ./src/index.tsx
declare var Foo: any;
let x = <Foo></Foo>;

[4:24:35 PM] Starting compilation in watch mode...

src/index.tsx:3:9 - error TS17004: Cannot use JSX unless the '--jsx' flag is provided.

3 let x = <Foo></Foo>;
          ~~~~~

[4:24:37 PM] Found 1 error. Watching for file changes.

Now add "jsx": "react", to the tsconfig.json.

  {
      "compilerOptions": {
+         "jsx": "react",
          "target": "esnext",
          "module": "commonjs",
          "noEmit": true,
      }
  }

Expected: Error should be gone.
Actual: Error is still present.

Hm, can you try the beta or nightly? I think this was fixed in #53403 and this issue is an accidental dupe of #53391.
