Required VS Code reload to see Copilot as issue assignee option

[bamurtaugh]

After running into #7035, I enabled the Coding Agent for my repo.

But I still don't see Copilot as an option:

I tried closing and reopening the issue, and using the refresh button in the Issues viewlet, but nothing changed.

I then reloaded VS Code entirely and reopened the issue, and now I see Copilot as an option:

It'd be great if there was a more automatic path to detecting / refreshing this.

If you'd opened the quick pick a second time it would have shown. We cache the users and refresh them in the background when you open the quick pick.
