+/// The existence of this PlaymodeMetdataCollector class in the PerformanceBenchmark tests is a hack to
+/// enable collection of test metadata when IL2CPP scriptingbackend is enabled. This same script is used in the
+/// performance testing extension and works fine when mono scriptingbackend is used. However, not so much for IL2CPP
+/// is used. This issue (most likely a JSON deserialization/stripping issue) is being investigated, but for now,
+/// if you want to ensure test run metadata is included in the result when using IL2CPP, include this class/test in your project.
