Repro Code

class T {
  /** @deprecated */
  #foo = () => {
    // ...
  };

  bar() {
    // should report but doesn't
    this.#foo();
  }
}

ESLint Config

module.exports = {
  parser: "@typescript-eslint/parser",
  rules: {
    "@typescript-eslint/no-deprecated": ["error"],
  },
};

tsconfig

{
  "compilerOptions": {
    "strictNullChecks": true
  }
}

Expected Result

I expected the rule to report this, since TypeScript also shows this as deprecated.

Actual Result

This wasn't reported by the rule.
