Maybe you can submit it to firefox as an error in there stuff or at
least a test case.

We took this route and implemented a javascript viewer 
as we wanted to mark up the images with other metadata.  
We needed to ability to draw certain type of shape and track 
information on the image and it appeared that SVG though
the right technology for this, was not stable enough to be useful.
Hopefully the SVG support will improve rapidly and we can 
return to that route.
