title: How to change text of Element Inspector tooltip/highlight via Chrome Extension?
body: <p>I would like to change the tooltip text of of Chrome's Element Inspector. (The one you see within the page when hovering a node in the tree view). I want to add additional information there.</p>
  
  <p><img src="https://i.stack.imgur.com/nDf1s.png" alt="Chrome Debugger highlight + tooltip"></p>
  
  <p>Is this somehow possible? I could not find any information in the docs.</p>
  
  <p>Alternatively creating a new little tooltip at another corner of the highlight rectangle (which will not interfere with the existing one) would be fine too. Thanks for any hints &amp; tips.</p>
