Issue when loading Google Docs with embed in Electron

Question

What is the reason for the error 'ERR_BLOCKED_BY_RESPONSE' when loading Google documents from Electron to embed? Tested in Chrome, no problem.

render() {
  return <div>
    <header />
      <iframe src="https://docs.google.com/spreadsheets/d/...g/edit#gid=0"></iframe>
    </header>
  </div>
}
