Hi Team,

While going through few files, I noticed that the [SameObject] is missing from following:

* Source/WebCore/svg/SVGAnimatedLengthList.idl:

It should be:

[SameObject] readonly attribute SVGLengthList baseVal;
[SameObject] readonly attribute SVGLengthList animVal;

As per spec: https://svgwg.org/svg2-draft/types.html#InterfaceSVGAnimatedLengthList

* Source/WebCore/svg/SVGAnimatedNumberList.idl:

[SameObject] readonly attribute SVGNumberList baseVal;
[SameObject] readonly attribute SVGNumberList animVal;

As per spec: https://svgwg.org/svg2-draft/types.html#InterfaceSVGAnimatedNumberList

* Source/WebCore/svg/SVGAnimatedRect.idl:

[SameObject] readonly attribute SVGRect baseVal;
[SameObject] readonly attribute SVGRect animVal;

https://svgwg.org/svg2-draft/types.html#InterfaceSVGAnimatedRect

^ As per spec, it should be DOMRec and DOMRectReadOnly as well.

* Source/WebCore/svg/SVGImageElement.idl:

[SameObject] readonly attribute SVGAnimatedLength x;
[SameObject] readonly attribute SVGAnimatedLength y;
[SameObject] readonly attribute SVGAnimatedLength width;
[SameObject] readonly attribute SVGAnimatedLength height;
[SameObject] readonly attribute SVGAnimatedPreserveAspectRatio preserveAspectRatio;

As per spec - https://svgwg.org/svg2-draft/embedded.html#InterfaceSVGImageElement

There might be more cases but just highlighting few examples.

Thanks!
