Repro Code

// Fails with "'args' is already declared in the upper scope on line 2 column 65."
function testFail1<F extends (...args: any[]) => any>(fn: F, ...args: any[]) {
	return [fn, args];
}

ESLint Config

module.exports = {
  parser: "@typescript-eslint/parser",
  rules: {
    "no-shadow": "off",
    "@typescript-eslint/no-shadow": "error"
  },
};

tsconfig

{
  "compilerOptions": {  }
}

Expected Result

I expect no errors.

Actual Result

I get the error 'args' is already declared in the upper scope on line 2 column 65.

Additional Info

The argument name in the generic has no effect on the rest of the code. Granted, it's a bit confusing to read, because the two args are completely unrelated, but there's no shadowing going on here.
