New Conversation button does not clear conversational variables in AI Chat

Summary:

I noticed a difference in the behavior of the New Conversation button between Debug Mode and AI Chat.

In Debug Mode, clicking New Conversation immediately clears all values assigned to variables with Conversational-level scope, and the new conversation starts with a clean state.

However, in AI Chat, clicking New Conversation does not clear the previously assigned conversational-level variable values. The values continue to persist in the new conversation.

The variables are cleared only after closing/reopening the chat and then starting a new conversation.

Is this expected behavior or a known issue in AI Agent Studio? If it is expected, what is the recommended way to reset conversational-level variables when the user clicks
