RSRP-288211: Unit Tests ignore NUnit TestCase with similar array arguments

Using ReShaper "Unit Test Sessions" runner.
On an NUnit [TestFixture], if the [TestCase] uses an array argument, then other cases with the same non-array arguments are ignored, as if they are duplicates.

Example.

    [TestFixture]
    public class TestEnumerableExtensions
    {
        [TestCase("Apple", new string[] { "Apple" })]
        [TestCase("Apple", new string[] { "Banana" })]
        [TestCase("Banana", new string[] { "Banana" })]
        public void ShouldGetFirstItemCorrectly(string expectedResult, IEnumerable<string> items)
        {
            var first = items.FirstOrDefault();
            Assert.AreEqual(expectedResult, first);
        }

In the runner it only lists 2 tests, even though there are 3:

• ShouldGetFirstItemCorrectly("Apple", System.String[])
  
• ShouldGetFirstItemCorrectly("Banana", System.String[])

If the tests are executed 'Run All', then the 2 tests succeed.
If the tests are executed 'Debug All', then all 3 tests are run and the 2nd fails as expected.
If the test project is executed under NUnit test harness, then all 3 tests are run and the 2nd fails as expected.
If a dummy argument is added to the tests, different value for each, then they all display.

Amni.
