'MarshalInterface<IStringable>' does not contain a definition for 'CopyAbiArray'

Looks like this PR introduced the scenario we should probably be handling but aren't: https://github.com/microsoft/TestWinRT/pull/29/files specifically

delegate Windows.Foundation.IStringable[] Array16Handler(Windows.Foundation.IStringable[] a, ref Windows.Foundation.IStringable[] b, out Windows.Foundation.IStringable[] c);

Trying to build the project gives the following error(s):
