Steps to reproduce
When I try to flatten a two-dimensional array by Enumerable.SelectMany method with generic type arguments, the first type argument int[] may not be treated correctly.
[Linq.Enumerable]::SelectMany[int[], int](
[int[][]] @((,2), (,4), (,6), (,8)),
[Func[[int[]], int[]]] { param ($x); $x }
) | ConvertTo-Json -CompressExpected behavior
[2,4,6,8]Actual behavior
