Seems like this mutation causes incorrect object reference to be patched with wrong data:

spreed/src/store/messagesStore.js

Lines 284 to 295 in 3197426

	addMessage(state, message) {
	if (!state.messages[message.token]) {
	Vue.set(state.messages, message.token, {})
	}
	if (state.messages[message.token][message.id]) {
	Vue.set(state.messages[message.token], message.id,
	Object.assign(state.messages[message.token][message.id], message)
	)
	} else {
	Vue.set(state.messages[message.token], message.id, message)
	}
	},

Resulting in replacing the message in store and in DOM tree (message id=2017713 dissapears, and message id=2017786 is duplicated):

2017713: {
    "id": 2017786,
    "token": "TOKEN",
    "actorType": "users",
    "actorId": "actor",
    "actorDisplayName": "...",
    "timestamp": 1689252346,
    "message": "> temporary messages has relatively longer id with prefix 'temp-'...",
    ...
},
...
2017786: {
    "id": 2017786,
    "token": "TOKEN",
    "actorType": "users",
    "actorId": "actor",
    "actorDisplayName": "...",
    "timestamp": 1689252346,
    "message": "> temporary messages has relatively longer id with prefix 'temp-'...",
    ...
}

Steps to reproduce

Algorithm for reproducing is not defined, as it happens sometime after fetching a new messages from server.
Upd: happens quite often for system messages:

Expected behaviour

Messages should not be duplicated
