Is there any chance you can add a failing test for this in https://github.com/wixtoolset/Core?

I'm not familiar with the new code structure...
Where's dark?

[rseanhall]

dark is now wix.exe decompile. You can see some decompiling tests in DecompileFixture. For the MSI's, we've been checking them in because most of them can't be created by WiX. For bundles, I would prefer that the test build the bundle and then decompile it since we don't have to deal with bundles created by third party software.

Added the test- wixtoolset/Core#204

dark doesn't support extracting detached containers, this only happens in your fork of WiX.
