SVG <use> elements in Chrome not displayed
===

Chrome seems not to display `<use>` elements in inline svg. Here is an example (code below or view it at http://www.bobwyttenbach.com/chromeuse.html):


    <!DOCTYPE html>
    <html>
    <head>
    <meta charset="utf-8">
    <title>Chrome use-tag bug?</title>
    </head>
    <body>
    <svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="200px" height="200px" viewBox="0 0 200 200">
    	<defs>
    		<g id="test1">
    			<circle cx="100" cy="100" r="50" fill="red"/>
    		</g>
    	</defs>
    	<g>
    		<rect x="0.5" y="0.5" width="199" height="199" stroke="black" fill="none"/>
    		<use xlink:href="#test1" x="0" y="0"/>
    	</g>
    </svg>
    <p>Above is inline svg with a use tag; below is the same svg linked through an object tag. Below is correct.</p>
    <object data="chromeuse.svg" width="200" height="200"></object>
    </body>
    </html>

The red circle does not appear in the inline svg but does appear when the same svg is linked through an object tag. Safari, Firefox, Opera, and Internet Explorer 9 all display the inline svg correctly.

Am I doing something wrong? Is this a known Chrome bug (I haven't found it listed)? Any workarounds?
