Globe key cannot switch to iOS emoji keyboard

Scenario: hardware keyboard is attached to iPhone

Before iOS 18.2, if I setup only two keyboards (e.g., english and emoji) in the system, click Globe key can switch to iOS emoji keyboard without problem. Since iOS 18.2, it stop working, and emoji keyboard is never displayed. I need to add one more keyboard, then I can switch to emoji keyboard (via the keyboard selector).
