Querying decimal into object results in truncation of data

Here is a test that reproduces it:

public void TestDecimalSelect()
{
    using (var connection = Program.GetOpenConnection())
    {
        connection.Execute("select cast(0.090 as decimal(5, 3)) test into tmp_test");
        var query = connection.Query<DecimalObj>("select top 1 test from tmp_test");
        decimal result = query.First().result;
        connection.Execute("drop table tmp_test");
        result.IsEqualTo(0.090m);

    }
}

class DecimalObj
{
    public decimal result { get; set; }
}

If you use connection.Query<decimal> without the object it works, and if if you 
select the decimal without the temporary table it also works.  But querying 
from a real table into an object with a decimal results in 0 being returned 
instead of 0.090.
