Title: Conversation History and Code Edits Lost When Using GitHub Copilot Chat

[aldayg1]

Description:
When using Visual Studio Code with only the GitHub Copilot extension enabled, I notice that my Copilot chat conversation history is lost after certain actions (such as restarting VS Code or after a period of inactivity). Additionally, sometimes code edits made during the session are reverted or lost unexpectedly.

Steps to Reproduce:

1. Open VS Code with only GitHub Copilot enabled.
2. Start a Copilot chat session and make some code edits based on suggestions.
3. Close and reopen VS Code, or leave it idle for a while.
4. Observe that the chat history is missing and/or some code edits are reverted.

Expected Behavior:
Chat history and code edits should persist across sessions and not be lost unexpectedly.

Additional Info:

• OS: Windows
• VS Code
• Copilot extension
• No other extensions enabled

Please advise if this is a known issue or if there are any workarounds.

Does this issue occur when all extensions are disabled?: Yes/No
