Nested web.*.configs aren't transformed upon deployment

If I have a web solution that has the following structure:
~/default.aspx
~/web.config
~/web.Debug.config
~/web.Release.config
~/services/web.config
~/services/web.Debug.config
~/services/web.Release.config

When running Publish-Interactive.ps1 and specifying "Release" as the transform to apply, only the root web.config is transformed. No other transformations are applied to nested web.configs.
