Problem
The full-V8 package test webscene_css_property_identity_tests fails because specified_property_samples includes animation-direction, animation-fill-mode, and animation-play-state, while the authoritative metadata intentionally classifies those names as storage-only rather than typed css_property_id entries.
This was exposed by run 35510426945 after the compiler/link blockers were removed. Runtime support for all three properties is present; the failure is an invalid typed-IR coverage claim.
Fix
- remove storage-only animation properties from the typed specified-value sample catalog;
- keep their CSSOM exposure and retained runtime behavior unchanged;
- update the exact typed-sample cardinality assertion;
- add/retain an explicit check that the three properties remain in the storage-only catalog, so the test cannot silently stop covering their classification.
Acceptance
The focused property identity executable passes, metadata generation stays reproducible, and animation direction/fill/play functionality remains exposed without assigning unstable typed cache identities.
