Using both [RunsOnUIThread] and [DynamicData] won't run data source on UI Thread

[carldebilly]

The dynamic data provider should run on the same context (UI Thead here) than the test itself.

[TestClass]
public class SomeTests
{
    [TestMethod]
    [RunsOnUIThread]
    [DynamicData(nameof(GetTestsData), DynamicDataSourceType.Method)]
    public Do_The_Tests(FrameworkElement element)
    {
        // Do something with the `element`
    }

    public IEnumerable<object[]> GetTestsData()
    {
        var stackPanel = new StackPanel();
        stackPanel.Children.Add(new Border()); // WILL CRASH HERE
        yield return [ stackPanel ];
    }
}
