When script optimizations are enabled, classes containing downlevelled static properties are wrapped in a pure annotated IIFE to allow the class to be removed if it is otherwise unused. Only properties with initializer values that do not have the potential for side effects can be safely wrapped. Previously, pure annotations were not considered when analyzing the values and this caused classes to be retained that could be considered safe for removal. To resolve this issue, pure annotations are now considered when analyzing a property's initializer value for potential side effects.
