Issue when building with cache and NuGet dependencies

[slogsdon]

When building a project with cache present and NuGet dependencies, some modules (internal and external) throw errors during compilation:

~To make things more interesting, this happens when attempting to convert the Elmish React template output from webpack to parcel, but does not happen when adding new packages to this project's included example.~

Edit: this ended up being incorrect. Adding Fable.React only did not cause the issue, but once Fable.Elmish and Fable.Elmish.React were added, the issue returned:
