295589 - getBBox() does not work when SVGLoad event is fired

Status: RESOLVED DUPLICATE of bug 293581

(Core :: SVG, defect)

Description

[Peter Thompson]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.0.3705)
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv: 1.8b2) Gecko/20050523 Firefox/1.0+

The file in the expected results area can be used to duplicate the problem.  
When you load the file in IE/ASVG3 and Squiggle, the 'click here' text is 
blue.  When you load the file in Firefox/Moz, the 'click here' text is red and 
there is an exception shown in the JavaScript console indicating that the 
getBBox() call in the onload event handler caused an NS_ERROR_FAILURE.

Here is some text from SVG 1.1 about the SVGLoad event:

  The event is triggered at the point at which the user agent has fully
  parsed the element and its descendants and is ready to act
  appropriately upon that element, such as being ready to render the
  element to the target device.

getBBox() works.  You can check that by clicking on the 'click here' text in 
any of the three SVG viewers mentioned above (the text changes to the x value 
of the bounding box).  getBBox() just doesn't work in the SVGLoad event handler.


Reproducible: Always



Expected Results:  
'click here' text should be blue, and no exception.
