Repro Code

export const mapObj = <K extends string, V, T>(obj: { [key in K]?: V }, fn: (key: K, val: V) => T) =>
  Object.entries(obj).map(entry => fn(...entry as [K, V]));

ESLint Config

module.exports = {
  parser: "@typescript-eslint/parser",
  rules: {
    "@typescript-eslint/no-unnecessary-type-parameters": "error",
  },
};

Expected Result

The rule should not report on V — V is used 3 times

Actual Result

The rule claims that V is only used once, when it's actually used 3 times.
