dotnet build can be more noisy with rtk

I created a simple dotnet console app with a deliberate compilation error:

Console.Write("Enter your name: ");
string name = Console.ReadLine();
Console.WriteLine($"Hello, {name}!");
error

dotnet build > output.txt

It looks like rtk produces the summary but also keeps the output. It only happens if the compilation fails. When the compilation succeeds, rtk only produces the summary, as expected.
