Duplicate ManagedToUnmanagedTransition and UnmanagedToManagedTransition calls in profiler

[ww898]

.NET 6.0. x64, Windows 21H2 x64 19044.1706

My question is about duplicate manaded-unmanaged transitions in profiler. Interop+User32+WNDPROC.Invoke() and Interop+User32+WndProc.Invoke() methods always reported twice:
