Too long parameters in TestFixtures on classes make the R# Test runner window behave weirdly...

Paramlengtherror.cs

using NUnit.Framework;

namespace Reproduce_resharper_error
{
    [TestFixture("Some param")]
    [TestFixture("Some longer param")]
    [TestFixture("Some slightly longer param")]
    [TestFixture("1234567890123456789012345678901234567890")] // Add one more char here, and it disappears from the test runner window
    [TestFixture("Some really, really, really, really, really, really, really, really long param")]
    [TestFixture("Some really, really, really, really, really, really, really, really, really, really, really, really long param")]
    public class Tests
    {
        private readonly string _param;

        public Tests(string param)
        {
            _param = param;
        }

        [Test]
        public void MyTestMethod()
        {
            Assert.IsNotNull(_param);
        }
    }
}
