dotnet nuget push doesn't push package when using wildcard

[senketsu03]

I dotnet pack my packages into publish/nuget directory and want to push everything in this directory to nuget. So, I ran it like so:

dotnet nuget push publish/nuget/*.nupkg -s https://api.nuget.org/v3/index.json -k $apiKey --skip-duplicate

However, I get an error: error: File does not exist (publish/nuget/*.nupkg).

After googling and several experiments, I tried out the following:

dotnet nuget push publish\nuget\*.nupkg -s https://api.nuget.org/v3/index.json -k $apiKey --skip-duplicate

And it worked. Does the first approach not work by design, or is it a bug?
