Y U NO RESIZE? bookmarklet

gistfile1.js

// put this in a bookmarklet
// click it as required

javascript: (function () {
  var style = document.createElement('style');
  style.innerHTML = '* { -webkit-text-size-adjust:auto; }';
  document.head.appendChild(style);
})();

If you have never created a bookmarklet, here's one way to do it:

• Bookmark this page right now.
• Edit the bookmark, and change the name to "Y U NO RESIZE?" (or whatever)
• While editing, change the URL to the code in lines 4 through 8 in the snippet above.

For more about making your own, I wrote a whole article about it:
