public static int TestSum(SharedArrayBuffer sharedArrayBuffer)
{
    Int32Array array = new Int32Array(sharedArrayBuffer);
    Span<int> nativeArray = array; // error                        
    
    int sum = 0;
    for (int i = 0; i < nativeArray.Length; i++)
    {
        sum += nativeArray[i];
    }

    return sum;
}

Fails with "Object '...' is not a typed array" in js_typed_array_to_array.
