title: Monaco-editor: disable all suggestions
body: <p>I am using Monaco to edit plain text and I want to disable all kind of suggestions.
  I disabled all suggestions options. However, when I press "CTRL + Space", monaco is still showing a popup with a message "No suggestions". See an example at <a href="https://codesandbox.io/s/monaco-suggestions-issue-hq1j9" rel="nofollow noreferrer">https://codesandbox.io/s/monaco-suggestions-issue-hq1j9</a></p>
  
  <p><img src="https://i.stack.imgur.com/uvD5y.png" alt="screenshot of suggestions"></p>
  
  <p>Does anyone know how can I disable this tooltip?</p>
