Commented Issue: Windows script engines leak host objects exposed via dynamic property assignment [47]

This issue was reported [here](https://clearscript.codeplex.com/discussions/545913). An initial investigation points at a bug in the Windows script runtime. A workaround may be to force the engine to call back to the host to retrieve the property value.
Comments: Fixed in [ClearScript 5.4](https://clearscript.codeplex.com/releases/view/135637).
