WPT: add [SameObject] identity coverage for SVGSVGElement.currentTranslate
https://bugs.webkit.org/show_bug.cgi?id=318044
rdar://180830216
Reviewed by Brent Fulgham.
SVG 2 declares currentTranslate on SVGSVGElement with the WebIDL [SameObject]
extended attribute, which requires the getter to return the same object on
every access. The existing WPT coverage for this corner of the SVG DOM is
reftest-only and visual (svg/struct/reftests/currentScale*); nothing asserts
the JS-observable identity requirement
svg.currentTranslate === svg.currentTranslate.
WebKit already satisfies this: currentTranslate is backed by a stable
Ref<SVGPoint> member returned by reference, so the same wrapper is observed on
every read. This adds a scripted testharness test that guards that behavior and
exposes the cross-engine divergence upstream.
The test isolates the readonly check on the attribute value rather than object
identity, so an engine that fails [SameObject] still passes the readonly subtest
if it honors readonly. No WebKit code change is required.
