Error when disposing unclosed transaction in session

[kzhui125]

Neo4j Version: 4.4.6 Enterprise
Neo4j Mode: Single instance
Driver version: .NET driver 5.0.0 dotnet: 6.0

Steps to reproduce

1. Run a query with await session.ExecuteReadAsync(Work).
2. when the function returns, because of the await using session = statement, so DisposeAsync is called.
3. I get exception
4. I can't reproduce now.

Actual behavior

I get exception: "Error when disposing unclosed transaction in session: Cannot rollback this transaction, because it has already been committed."

Why does the driver try to rollback the committed transaction when dispose the session?

When the transaction is committed, the session state in AsyncTransaction should be Committed, _transaction in AsyncSession should be null.

So I don't know how does this exception happen, is there a bug in the driver?

async ExecuteAsync()
{
    await using session = xx

    var tasksQuery = xxx
        .AsEnumerable()
        .Select(async xx => await session.ExecuteReadAsync xx);

    foreach (var task in tasksQuery)
    {
        // this break cause bug
        if (linkedToken.IsCancellationRequested)
            break;

        var taskResult = await task;
    }
}

because the break line, cause session dispose before transaction dispose

it's not neo4j driver bug...
