title: Provide a browser tab icon with a base24 data URL
body: <p>Usually to set an icon in the browser tab you use</p>
  <p><code>&lt;link rel=&quot;icon&quot; href=&quot;logo.png&quot;&gt;</code></p>
  <p>I want to embed the logo in the html file using a data URL, so something like</p>
  <p><code>&lt;link rel=&quot;icon&quot; href=&quot;data:image/png;base64,﻿iVBORw0KGgoAAAANSUhEUgAAAzcAAALUC...&quot;&gt;</code></p>
  <p>but it doesn't work. How can I get the base24 icon to appear in the tab.</p>
