CancellationTimeout is not respected on cancellation error
trafficstars
Software versions MySqlConnector version: 2.2.5 Server type (MySQL, MariaDB, Aurora, etc.) and version: MySQL 8.0 .NET version: 7.0
Describe the bug
This is a child issue from #1302.
When opening of cancellation connection results in an error, the cancellation is retried 10 times, each retry lasting for a duration of CancellationTimeout. This increases request latency to a huge amount of seconds, which affect metrics a lot, holds resources like threads, and so on.

Code sample
using MySqlConnector;
using MySqlConnector.Logging;
MySqlConnectorLogManager.Provider = new ConsoleLoggerProvider(MySqlConnectorLogLevel.Trace);
var cts = new CancellationTokenSource();
const string connectionString = "connection string with failing cancellation (for example, one with enabled ServerRedirectionMode)";
await using var connection = new MySqlConnection(connectionString);
await connection.OpenAsync();
await using var cmd = new MySqlCommand("SELECT SLEEP(5)", connection);
var task = cmd.ExecuteNonQueryAsync(cts.Token);
cts.Cancel();
await task;
Expected behavior
When I set CancellationTimeout to 2 seconds, I expect the cancellation to last for a maximum of 2 seconds instead of 10*2 seconds. I expect cancellation tobe respected, or at least being able to configure the retry count of 10.
Additional context
Here is the code responsible for the 10 retries: link.
Subsequent retries are executed because of RegisterCancel(). I have logged the stack trace via Log.Trace($"Executing RegisterCancel:\n{System.Environment.StackTrace}");, here is the stack trace from subsequent calls (first one is called from the test script as planned):
