”where in“ parameter splicing problem

Parameter 'sqlParams111' has already been defined."

demo as follows:

//test_01 and test_11 only contain two fields id and addtime
try
{
    using (var conn = new MySqlConnection(connStr))
    {
        conn.Open();
        var ids1 = new List<int> { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 };
        var ids2 = new List<int> { 1, 20, 18, 17 };
		
        var sql = @"
                select addtime from test_01 where id in @sqlParams1
                union all 
                select addtime from test_11 where id in @sqlParams11";
				
        var res = conn.Query<DateTime>(sql, new { sqlParams1 = ids1, sqlParams11 = ids2 }).ToList();
        res.ForEach(s => Console.WriteLine(s));
        Console.ReadKey();
    }
}
catch (Exception ex)
{
    throw;
}

No source file or test is named. Start by reproducing the supplied C# query with two differently named IN parameters, then trace Dapper's parameter-splicing path for collection parameters. Done means both collections execute without the duplicate-parameter error and the behavior is covered by a regression test.
