MySql.Data version 8.0.31 doesn't set right isolation level

When using MySql.Data version 8.0.31 with .Net 6.0, when the isolation level is set for a command, the command is executed at the default isolation level.

The sample below demonstrates the issue:

public void TestBuggyIso()
var connection = new MySqlConnection(ConnectionString);
var transaction = connection.BeginTransaction(System.Data.IsolationLevel.Serializable);
MySqlCommand command = new("SELECT @@transaction_isolation;", connection, transaction);
var reader = command.ExecuteReader();
while (reader.Read())
string value = reader.GetString(0);
Assert.AreEqual(value, "SERIALIZABLE");

Here the isolation level should be Serializable but I see that the isolation level is set to REPEATABLE-READ.
