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