Background
Passing
id: undefinedtouseChatcauses the internalChatinstanceto be recreated on every render, wiping all messages and in-flight streams.
This is a common pattern:
id={conversationId ?? undefined}.Fixes #16226
Summary
Added a nullish check (
options.id != null) to theshouldRecreateChatcondition so that
id: undefinedis treated the same as omittingid.Checklist
