Description

I recently updated MSTest adapter to version 2.2.5 from 2.2.3 and noticed following change in behavior of results of data driven tests.
There are results for individual data rows, but they are missing parent test. Therefor results arent structuralized and I cant tell which data row result belong to which test.
I would like to know if this is a bug or expected behavior.

Steps to reproduce

1. Create simple test project targeting .net framework 4.8 or .net core 3.1
2. Get MSTest framework and adapter 2.2.5+
3. Create these simple data driven tests:

        [TestMethod]
        [DataRow("1", DisplayName = "A")]
        [DataRow("2", DisplayName = "AA")]
        public void Test1(string test)
        {
        }

        [TestMethod]
        [DataRow("1", DisplayName = "B")]
        [DataRow("2", DisplayName = "BB")]
        public void Test2(string test)
        {
        }

4. Run tests via cmd with /Logger:trx
5. Repeat steps but this time with MSTest Framework and adapter version 2.2.3
6. Compare trx files or console outputs

Expected behavior

This is result structure with adapter version 2.2.3 (sorry its not in English but the idea should be clear)

This is how trx file looks:

Actual behavior

This is result structure with adapter version 2.2.5 (sorry its not in English but the idea should be clear)

This is how trx file looks:
