title: SVG Gradient turns black when there is a BASE tag in HTML page?
body: <p>I am using the Raphaël JavaScript Library to create SVG elements in an HTML page and using CodeIgniter as a PHP framework. In the CodeIgniter framework I need to add a <code>&lt;base&gt;</code> tag in the head of the HTML document to use JS,CSS and images, but it caused a strange problem in the SVG element.</p>
  
  <p>When I use the <code>&lt;base&gt;</code> tag, gradients do not work. Instead, the object turns black. It behaves exactly the same with image filled path objects.</p>
