MSTests run in Visual Studio, but not via dotnet test

Question

https://github.com/mrpmorris/AutoRegister (deleted-tests branch)

My unit tests project has a project reference to Morris.AutoRegister.Fody. When I run the tests in Visual Studio they work fine, but when I run them via dotnet test in the Source folder I get the following error for every test...

C:\Data\Mine\Code\AutoRegister\Source\Lib\Morris.AutoRegisterTests\ModuleWeaverTests\AutoRegisterAttributeTests\FindTests\ServiceTypeFilterTests.cs(31): error test failed:
      WhenAServiceTypeFilterIsSpecified_ThenOnlyServiceTypesMatchingThatFilterAreRegistered (1ms): Test method Morris.Au

      erIsSpecified_ThenOnlyServiceTypesMatchingThatFilterAreRegistered threw exception:

UPDATE

1. If I build the app in VS and then execute dotnet test --no-build then the test runs and passes.
2. If I execute dotnet test --no-restore then it rebuilds and still works.
3. If I execute dotnet test it restores + rebuilds and then fails.
4. I spotted the following diff in Morris.AutoRegisterTests.deps.json
