When uploading SVG file, the tag
Example:
SVG file that I upload:
<svg height="661" width="1322" xmlns="http://www.w3.org/2000/svg">
<circle id="myCircle" cx="5" cy="5" r="4" stroke="blue" />
<use href="#myCircle" x="20" fill="white" stroke="red" />
</svg>
What gets uploaded looks like this:
<svg height="661" width="1322" xmlns="http://www.w3.org/2000/svg">
<circle id="myCircle" cx="5" cy="5" r="4" stroke="blue" />
</svg>
