svg creates http instead https on non-absolute URL
<p>I'm using SVG on a page using HTTPS, but SVG creates an HTTP instead of HTTPS link to an image, causing that the browsers treat the page insecure. SVG is used with the following fragment:</p>

<pre><code>&lt;svg id="head-image-1000" width="1000" height="130" xmlns="https://www.w3.org/2000/svg" xmlns:xlink="https://www.w3.org/1999/xlink"&gt;
    &lt;g&gt; 
        &lt;a xlink:href="/"&gt;
            &lt;image xlink:href="/layout/panorama-winter-1400.jpg" height="97" width="1000" y="0" x="0"/&gt;
        &lt;/a&gt;
    &lt;/g&gt;
&lt;/svg&gt;
</code></pre>

<p>Is the only possibility to use absolute URL?</p>
