Could you see all your messages from all your clients ? about wire-server HOT 1 CLOSED

The sending client receives an answer, if any, in the HTTP response payload. Its own payload is not persisted in the backend (you know the plaintext message you send at the time, it makes no sense to encrypt for yourself, persist in the backend, and re-download the message for your own client. Encryption sessions need two distinct client Ids AFAIK). The difference in observed behaviour between sending and receiving clients in the light of deleted IndexedDBs is to be expected. The backend filters out any client payloads if they are superfluous. If your example payload above included userC: clientC but this user isn't in the corresponding conversation, that user would not get a message. You can see this by inspecting the resulting HTTP response from your request (it gives feedback on deleted/unused/superfluous client payloads).

Functioning client functionality without message loss when manually wiping IndexedDB is not a feature Wire supports.

I hope that answers your question? If not, please re-open this or another issue with clarifying questions.
