TTS with a question... the audio back has the answer

bug

I just tried, and can confirm this bug seems to be tied to gpt-4o-mini-tts-2025-12-15. It responds with all sorts of reactions as if it were answering instead of speaking.

The previous snapshot works correctly though, so for now if you use gpt-4o-mini-tts-2025-03-20 it works fine.
