SkipLibCheck fails to work in multi-project set-up

TypeScript Version: 3.8. Beta

Search Terms:
skiplibcheck

Steps to reproduce

1. Extract the attached zip file to a folder and open repro.sln in Visual Studio (I'm using 2019)
2. Expand the npm folder on project B and install the missing @azure/storage-blob package.
3. Rebuild the solution.

Expected behavior:
No build errors.

Actual behavior:
2 errors:

error TS2740: Build:Type 'Buffer' is missing the following properties...
error TS2345: Build:Argument of type 'ErrnoException' is not assignable...

Explanation
We want have a custom definition for NodeJS. The npm package imported in Project B also has its own (incomplete) definition. So, we've added skiplibcheck to all the projects.

Project B builds fine by itself.

Project C references some NodeJS types. Project C also builds fine by itself.

Project A references types from both B and C.

When attempting to build A, we get the error above. But the error is for project C.

Basically, when building Project A, the skiplibcheck option is being ignored and the incomplete NodeJS definition from the imported package is being used.

Further Observations
Curiously, if file A/foo/bar.ts is moved to A/bar.ts (and the imports amended) the build compiles fine.

Attachment
Repro.zip

Extrae Repro.zip y abre repro.sln en Visual Studio; después, vuelve a compilar la solución con los proyectos A, B y C. Compara el comportamiento cuando A/foo/bar.ts se mueve a A/bar.ts e inspecciona la configuración del proyecto relacionada con skiplibcheck. Se considera terminado cuando la compilación multiproyecto se completa sin los errores TS2740 y TS2345 indicados.
