Accept button on floating window doesn't work

I'm experiencing a weird problem that on the suggestion floating window, the `Accept` button doesn't work. When I click on it, nothing happens. The suggestion isn't applied to the code, and the floating window doesn't disappear either.


The reject button works as expected that no code changes and the floating window disappears.

I can accept it from Menu bar though


But since it's too inconvenient so I've set a key binding to accept it as a workaround.

Is there anybody having the same problem?

My environment:
- Chip: M1 Max
- macOS: 13.2.1（22D68）
- Xcode: 14.2 (14C18)
- Copilot for Xcode: 0.8.6 (49)

Start by reproducing the failure in the suggestion floating window using the reported macOS, Xcode, and Copilot for Xcode versions, then compare the floating-window Accept action with the working menu-bar action. Done means Accept applies the suggestion and dismisses the floating window, while Reject continues to behave as reported.
