Timeout on TestFixtureSetup does not seem to work

[phasemaster]

In the following setup, I expect the TestFixtureSetup to be aborted by a timeout:

    [TestFixture]
    public class TestRun
    {
        [TestFixtureSetUp, Timeout(20000)]
        public void ClassSetUp()
        {
            Console.WriteLine("Starting TestFixtureSetUp");
            for (int i = 1; i <= 120; i++)
            {
                Thread.Sleep(1000);
                Console.WriteLine("{0} seconds", i);
            }
        }

        [Test, Timeout(25000)]
        public void TheTest()
        {
            Console.WriteLine("Starting Test");
        }
    }

It is not. Why?

Timeout on a test fixture sets the default timeout for each method. There is no timeout setting for fixtures. Per https://github.com/nunit/docs/wiki/Timeout-Attribute...

"The attribute may also be specified on a fixture or assembly, in which case it indicates the default timeout for any subordinate test cases."
