Ignore tree-scope when matching container-name for @container queries. Previously, container-name matching for container queries used tree-scoped names/references for matching, which meant the same name would not match if the @container rule and the container-type property were originating from different trees such that that container-type declaration came from an inner shadow tree. With this change container names match regardless of @container rule or container-type declaration origins.
Aligning with the spec change and Firefox implementation.
