After transferring group ownership to another member, attempting to leave the group triggers owner-only prompts (e.g., “who do you want to transfer ownership to?” or “the group will be ownerless”). The system continues to treat the previous owner as the current owner. In some cases, the newly assigned owner can’t make certain group changes for 1–2 days.
Steps to Reproduce:
1. As the current group owner, transfer ownership to Member B.
2. Confirm Member B is shown as the new owner (UI indicates transfer succeeded).
3. Attempt to Leave Group.
4. Observe that owner-only prompts appear (e.g., select a new owner / warning that the group will be ownerless).
5. (Sometimes) Have Member B try to change group settings or permissions shortly after the transfer.
