When adding two steering message the first gets queued which messes up order.

Describe the bug

When steering, and then you have another idea and steer again, the order of the steering messages is flipped and the first message is queued. Leading to the wrong order of execution.

This happens a lot when you think of relevant context after firing off the steering message.

Affected version

GitHub Copilot CLI 1.0.78. Run 'copilot update' to check for updates.

Steps to reproduce the behavior

1. Start a task in copilot CLI
2. Give it a steering message
3. Before it's finished processing steer again, e.g. adding more context

This leads to the first steering message being queued, and the second steering message being used now, which would even be confusion for a human.

Expected behavior

Steering happens in the order we steer, and is not queued without asking to queue.

Additional context

• OS: MacOS
• Shell: Nushell
• Terminal: Ghostty (seems to have with normal Mac terminal as well though)

Commencez par reproduire le comportement dans Copilot CLI 1.0.78 : envoyez un message de steering, puis un autre avant la fin du traitement, en suivant les étapes de l’issue. Suivez le traitement des messages de steering et le point d’entrée de la file d’attente, puis vérifiez que les messages de steering sont exécutés dans l’ordre d’envoi et ne sont pas mis en file d’attente sans demande explicite.
