BindingsGenerator: Handle global interfaces without named properties DedicatedWorkerGlobalScope is an object with a Global extended attribute, but does not define any named property getters. This needs to be handled by setting the prototype chain to: DedicatedWorkerGlobalScope ^ DedicatedWorkerGlobalScopePrototype ^ WorkerGlobalScopePrototype (This is different from something like Window, where there is an intermediate WindowProperties object for named properties.) Previously, we treated the GlobalMixin object as if it was a simple prototype object, accidentally setting DedicatedWorkerGlobalScope's prototype to WorkerGlobalScopePrototype. This caused the expression self instanceof DedicatedWorkerGlobalScope to return false inside workers. This makes us pass many more of the "/xhr/idlharness.any.worker" WPT tests than before, rather than failing early. 2024-10-12 13:52:10 +00:00			`onmessage = function (event) {`
