How does Firefox handle xml:base when generating GET requests for SVG image elements?

I am loading an SVG image at the following URL:

http://localhost/howl/svg/id/543

The source for this SVG code is:

<svg xml:base="/howl/"> 

 <svg width="535" height="325" xmlns="http://www.w3.org/2000/svg"

xmlns:xlink="http://www.w3.org/1999/xlink"> 

   <image xlink:href="file/id/532" />
 </svg>

</svg>

As you can see, the SVG code is located at one path, but the <image> is relative to the root, hence the wrapping xml:base attribute.

The actual requests in Firefox, according to Tomcat Logging are:

GET /howl/svg/id/543 GET /howl/file/id/532

However, Firebug's Net tab shows these requests:

GET /howl/svg/id/543 GET /howl/svg/id/file/id/532 (Incorrect, doesn't happen) GET /howl/file/id/532

When I test the same thing in Safari and Chrome, all three GET requests actually happen, the incorrect one resolving in a 404.

I suspect that Firefox is generating all three requests, but discarding the incorrect one and Firebug is not aware of this. As a result, Firebug shows all three requests, but the incorrect one never resolves.

So, I'm curious about the behavior or whether I am doing this incorrectly.

Thanks!
