I was experimenting with SVG images and I was experiencing that Firefox hangs on a very huge SVG image when you select 'Select all' from the right-click context menu. The GUI is locked immediately.

1. Open test case at the URL provided above
2. Right-click the SVG image
3. Experience Firefox to hang
Actual Results:  
Firefox hangs, no GUI responses

Expected Results:  
Execute 'select all' command

Following these steps results in a hang of about 2 seconds then resumes to normal. 

Could we get more information on the complexity/size of this SVG file?  Is there a way to verify that this bug is truly based on Firefox and not system specifications?  large SVG files which do take time to render such as

Cause no GUI freeze when executing the "Select All" command
