Bug 256316 – Sync 'SVGClipPathElement' with IDL Spec and add 'transform' as well

• Component: SVG
• Status: RESOLVED FIXED

[Ahmad Saleem]

Hi Team,

While going through WPT failures, I noticed that we fail following interop tests from CSS-Masking:

Test - https://wpt.fyi/results/css/css-masking/idlharness.html?label=experimental&label=master&product=chrome&product=firefox&product=safari&aligned=&view=interop&q=label%3Ainterop-2023-cssmasking

We have three failures as follow:

SVGClipPathElement interface: existence and properties of interface object
SVGClipPathElement interface: existence and properties of interface prototype object
SVGClipPathElement interface: attribute transform

______

While going through IDL file:

WebKit Source - https://searchfox.org/wubkat/source/Source/WebCore/svg/SVGClipPathElement.idl

Web-Spec - https://drafts.fxtf.org/css-masking/#InterfaceSVGClipPathElement

________

We are missing following:

1) Interface to SVGElement rather than 'SVGGraphicsElement' as per spec:

interface SVGClipPathElement : SVGGraphicsElement

2) Missing 'transform' as per spec.

___________

Just wanted to raise this bug so we can track this failure.

Only Firefox is passing this and Chrome is also failing these three tests.

Thanks!

Forget to add that changing IDL file as per spec make us pass all three failing tests. Although I am not sure whether there will be any failures on WPE or GTK etc. or any bindings test or not.

CCing - Chris & Ryosuke for any input on this IDL file change, whether just updating IDL is enough or we have to do more.
