Andreas Kling b5babda288 LibWeb: Cache UniversalGlobalScopeMixin pointer on ESO ... Avoid expensive cross-hierarchy dynamic_cast from JS::Object to UniversalGlobalScopeMixin on every microtask checkpoint. Since UniversalGlobalScopeMixin is not in the JS::Object inheritance chain, as<UniversalGlobalScopeMixin>(JS::Object&) falls through to dynamic_cast, which is very costly. Profiling showed this taking ~14% of total CPU time. Add EnvironmentSettingsObject::universal_global_scope() backed by a pointer cached eagerly during initialization.		2026-03-24 08:28:47 +01:00
