Project Blueprints cannot be excluded from being nativized using the ExcludedAssets setting

The ExcludedAssets setting in the DefaultEngine.ini file does not appear to actually exclude a project Blueprint from being nativized.

1. Create a new code project using the First Person template.
2. Build the project in Visual Studio.
3. Open the DefaultEngine.ini file in the project's Config folder.
4. Add the following lines to the bottom of the .ini file:

   [BlueprintNativizationSettings]
   +ExcludedAssets=/Content/FirstPersonCPP/Blueprints/FirstPersonProjectile
   

5. Open the project in the Editor.
6. Open the Packaging Settings window and set the Nativization option to Inclusive.
7. Package the project for Win64.
8. Once the packaging process completes, navigate to <Project Name>\Intermediate\Plugins\WindowsNoEditor\NativizedAssets\Source\NativizedAssets\Public

RESULT:
There is a file present for the First Person Projectile Blueprint.

EXPECTED:
There is no file present for the First Person Projectile Blueprint.
