Static Method mocking when running test at class level

I found that if I run tests that involve static method mocking at class level, the static method may not work.

Here's the code:

    public class MyVerification
    {
        public static bool WithinRange(int value, int min, int max)
        {
            return false;
        }
    }
    [TestFixture, ClearMocks]
    public class TypeMockTest
    {
        public  TypeMockTest()
        {
            
        }

        [SetUp]
        public void Init()
        {
            Isolate.WhenCalled(() => MyVerification.WithinRange(0, 0, 0)).WillReturn(true);
        }

        [Test, Isolated]
        public void Hello1()
        {
            
        }

        [Test, Isolated]
        public void Hello2()
        {
            Assert.IsTrue(MyVerification.WithinRange(0, 100, 1000));
        }
    }

Now, if I run Hello2 individually, using Testdriven.net, then the test will pass, this is the expected behavior.

But if I run the test on the whole class TypeMockTest by placing the mouse cursor at the TypeMockTest and click run test, the Hello2 test will fail because the MyVerification.WithinRange is not mocked.
