Cannot use a custom $(PackageId).props or targets file in a razor class library project

Describe the bug

If I add my own props file with the name $(PackageId).props following the instructions in https://learn.microsoft.com/en-us/nuget/concepts/msbuild-props-and-targets, the content of it does not get included in the nuget package. Even a targets file is not packaged and neither is an analyzer/source generator from another project gets included. All of these just work when the project is not a razor class library.

I did not try including mvc views/pages in the razor class library project.

Expected Behavior

The nuget package should contain the props file with content included in the one in the project. Any analyzer/source generator should also be included in the package.

Steps To Reproduce

• Create a razor class library (without MVC support).
• Add props file with some custom properties (in PropertyGroup element) to the project following the instructions in https://learn.microsoft.com/en-.us/nuget/concepts/msbuild-props-and-targets.
• Run dotnet pack from CLI.
• Examine the built nuget package file in an archive manager.
• Observe that the build folder has the prop file but does not have the custom content added to the props file in the project.
