509892 - Some elements specified under the SVG namespace don't inherit nsIDOMSVGElement

Status: RESOLVED INVALID

(Core :: SVG, defect)

Description

[Paul Nickerson]

I don't know if this is a bug, but it's inconsistent with how HTML and XUL elements behave. SVG elements with the following node names dont inherit nsIDOMSVGElement:
ALTGLYPH, ALTGLYPHDEF, ALTGLYPHITEM, ANIMATE, ANIMATECOLOR, ANIMATEMOTION, ANIMATETRANSFORM, COLOR-PROFILE, CURSOR, DEFINITION-SRC, FONT, FONT-FACE, FONT-FACE-FORMAT, FONT-FACE-NAME, FONT-FACE-SRC, FONT-FACE-URI, GLYPH, GLYPHREF, HKERN, MISSING-GLYPH, MPATH, SET, TREF, VIEW, VKERN

<script>
var svg = document.createElementNS("http://www.w3.org/2000/svg", "svg");
document.documentElement.appendChild(svg);
var ce = document.createElementNS("http://www.w3.org/2000/svg", "any of the listed node names");
svg.appendChild(ce);
ce.QueryInterface(Components.interfaces["nsIDOMSVGElement"]);
</script>

Throws the following error:
Error: uncaught exception: [Exception... "Component returned failure code: 0x80004002 (NS_NOINTERFACE) [nsISupports.QueryInterface]"  nsresult: "0x80004002 (NS_NOINTERFACE)"  location: "JS frame :: file:///C:/mozilla/work/svgtest.htm :: <TOP_LEVEL> :: line 6"  data: no]

Support for these elements hasn't been implemented yet. When it is they will get the appropriate interfaces.

I'm going to mark this invalid as there are existing bugs on implementing the individual features.
