1511994 - SVGDefsElement.getBBox() exception

Status: RESOLVED DUPLICATE of bug 612118

(Core :: SVG, defect)

Description

[lviggiani]

Attachment: testcase.html

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:63.0) Gecko/20100101 Firefox/63.0

Steps to reproduce:

Try to execute the testcase.html attached to this bug.
The test case walks through a SVG tre and prints out the bbox of all SVGGraphicsElement.
As <defs> (SVGDefsElement) inherits from SVGGraphicsElement, the getBBox method is executed on that element too.


Actual results:

I Firefox getBBox() gives a NS_NETWORK_ERROR when executed on a SVGDefsElement, whereas in Webkit it simply returns a 0x0 box, without any error.


Expected results:

IMHO, SVGDefsElement should not inherit from SVGGraphicsElement as it does not make any sense having a getBBox method or getCTM etc as it is not an actual graphics element.
BTW, since it's like that, at least calling those methods on <defs> element should not trow errors.
