For the following code, the diagnostic is at the wrong position:

public sealed class MyTest
{
    [TestCase("string", 12, 27, "other")]
    public void Foo(string actual, Type expected, int value, string other)
    {
    }
}

Actual result (with 4.10.0):

Expected result
The squiggles should mark the 12.

This seems to happen if the number of parameters is four or more
