The CancellationToken in a TaskCanceledException on ToListAsync does not match

## Why does the `TaskCanceledException` to be the given one but it isn´t

```cs
using (MyDbContext dbContext = new())
{
CancellationTokenSource cts = new();
cts.Cancel();

try
{
await dbContext.People.ToListAsync(cts.Token);
}
catch (TaskCanceledException ex) when (ex.CancellationToken == cts.Token) // that is what I´m expecting
{
Console.WriteLine("No problem");
}
catch (TaskCanceledException ex) when (ex.CancellationToken == CancellationToken.None) // that is what is happening
{
Console.WriteLine("Why?");
}
}
```

Can you explain the given `cts.Token` is not passed to the exception?
