Expected Behavior

When navigating through previous conversations in a multi-model chat, the selection of a prior conversation should not alter or remove subsequent messages. All messages should remain visible and in their original order, regardless of which previous conversation is selected. New messages should always be appended to the end of the existing conversation.

Actual Behavior

Interacting with previous conversations causes inconsistent and unexpected behavior with subsequent messages, including deletion, temporary disappearance, and overwriting:

  • Scenario 1: General Selection of Previous Conversation: Selecting any previous conversation (by clicking on a message from that conversation) causes all subsequent messages to disappear.

  • Scenario 2: Partial Recovery: Selecting the first or last message of a specific, previously-selected conversation sometimes causes the disappeared subsequent messages to reappear. This is inconsistent.

  • Scenario 3: Message Overwrite:

    1. Select a previous conversation (causing subsequent messages to disappear, as in Scenario 1).
    2. While subsequent messages are hidden, send a new message.
    3. The new message does not cause the hidden messages to reappear.
    4. Now, attempt the recovery action from Scenario 2 (selecting the first/last message of the previously-selected conversation).
    5. The previously hidden messages reappear, but the new message sent in step 2 is gone (overwritten or permanently deleted).

  • Scenario 4: Successful Send:

    1. Select a previous conversation, disappearing messages after that conversation.
    2. Restore visibility of the messages by picking the first message from the prior conversation that caused the disappearing.
    3. Send the new message.
    4. The message is send normally and appears consistent in the conversation.

Steps to Reproduce

Scenario 1 (Disappearance):

  1. Start a multi-model conversation with multiple exchanges.
  2. Select a message from any previous point in the conversation (not the very last message).
  3. Observe: All messages after the selected message disappear.

Scenario 2 (Partial, Inconsistent Recovery):

  1. Follow steps 1-3 from Scenario 1 (messages disappear).
  2. Select the very first message of the conversation you selected in step 2.
  3. Observe: Sometimes, the disappeared messages reappear. Try selecting the last message of that same conversation; sometimes this also works. The behavior is unreliable.

Scenario 3 (Overwriting):

  1. Follow steps 1-3 from Scenario 1 (messages disappear).
  2. While the messages are hidden, type and send a new message.
  3. Observe: The new message is sent, but the other messages remain hidden.
  4. Attempt the recovery from Scenario 2 (selecting the first/last message).
  5. Observe: The previously disappeared messages reappear, but the new message sent in step 2 is gone.

Scenario 4 (Normal Send):

  1. Follow steps 1-3 from Scenario 1 (messages disappear).
  2. Follow the steps of Scenario 2 (message reappear).
  3. While the messages are visible, type and scend a new message.
  4. Observe: The new message is sent, and the other messages remain visible.

Additional Information

Workaround: After selecting a previous conversation (or interacting with the "Copy" button on a previous message), messages after that point may disappear. To attempt to recover the missing messages before sending any new messages, try the following:

  1. First, click on the first message of the previously selected conversation (the one that caused the messages to disappear).

  2. If that doesn't work, click on the last message of that same conversation.

  3. If messages still haven't reappeared, systematically click on other message blocks within that same previously selected conversation. Specifically, try clicking on messages:

    • From different models involved in that conversation.
    • From different points within that conversation (e.g., early messages, later messages).

  4. If messages haven't reappeared continue clicking on different message blocks, this time from different models involved on the whole conversation, and not only in the previously selected conversation.

This workaround is not guaranteed to work consistently, but it has been observed to sometimes restore the visibility of the missing messages. It is crucially important to attempt this recovery before sending any new messages, as sending a new message while the others are hidden will lead to data loss (overwriting).

Intended behaviour, you "select" a message to continue.
