Resuming a session is extremely slow, does not display UI that would indicate loading

Describe the bug

When I have several sessions in the left pane, even on the same device after restarting the CLI, resuming the session from the left pane is unbearably slow and has no loading UI. This is aggravating to use when I cannot tell if loading the session just isn't going to work at all or if it's slow. I've had it take up to a minute before.

Affected version

GitHub Copilot CLI 1.0.82

Steps to reproduce the behavior

1. Have multiple sessions present in the left pane
2. Restart CLI
3. Try to resume session, then try to resume another one
4. Notice severe delays between each of them being opened with 0 loading UI

Expected behavior

Expected sessions with fresh data to load quickly and with UX that distinguishes loading from a broken CLI

Additional context

No response

Commencez par reproduire le délai via le flux de reprise de session du volet gauche après avoir redémarré la CLI, en utilisant plusieurs sessions comme décrit. Suivez le chemin de reprise et observez quand le retour de chargement est absent ; le travail est terminé lorsque les sessions reprises ne semblent plus ne pas répondre et que l’état de chargement peut être distingué d’une CLI défaillante.
