Thanks for filing the issue.

The issue seems to be related to ASP.NET, which is out of scope for TE. Hence adding TE-NeedsTriageHelp label for further investigation of the issue.

Thanks.!

Just to clarify: The "this" duplicated local variables appears also on the Chrome Dev Tools Debugger. You just need ASP.NET to run the web-server.

Thank you for the issue! We'll take a look at this at some point, however it seems to be a very low priority issue.
