Error Messages/Logs

Bug: Chat area fails to render when switching back to a previously visited conversation; Cmd+R resolves it.
Observed behavior (via Proxyman):

First visit to a conversation: network request is sent and data returns correctly → renders fine.
Switching away and coming back: no network request is made — the app appears to look up a local cache or state instead, but fails to retrieve the data → blank render.

Suspected cause:
Likely a cache/state management issue on the second visit. Possible scenarios:

Cache key miss with no fallback to re-fetch
Race condition where the component mounts before state hydration completes
Stale Electron webview state causing subsequent fetches to be incorrectly deduplicated

Cmd+R forcing a full reload restores the conversation, suggesting the webview state is not being properly reset on conversation switch.

Steps to Reproduce

1. launch Claude desktop -chat
2. get into any history conversation, like A;
3. switch to another conversation, like B;
4. from conversation B switch back to conversation A;
5. conversation A not render
