Content of new node being replaced by existing node

[just-tom]

Describe the bug

Hi all,

I have a weird situation whereby when I add a new message/nodes to the end of my array the content showing is actually the content of another message somewhere else in the stack and not the message that I sent. However I can see in dev tools that the content of the latest node is correct.

I am assuming this is down to the virtualisation side, of which Im not too familiar, so probably something relatively simple to fix given the correct knowledge.

Reproduction

Heres the code as it stands. im using tailwind so you can see all styles applied:

<DynamicScroller
                v-if="messages.length"
                ref="scroller"
                :items="messages"
                :min-item-size="66"
                key-field="id"
                class=" px-2"
                :class="[pinnedMessage ? 'h-[36rem]' : 'h-[41.5rem]' ]"
            >
                <template v-slot="{ item, index, active }">
                    <DynamicScrollerItem
                        :item="item"
                        :active="active"
                        :size-dependencies="[item.text, item.reaction_counts]"
                        :data-index="index"
                        class=""
                    >
                        <Message :current-message="item" :stream-chat-channel="streamChatChannel" @show-mute-modal="showMuteModal = true" @show-block-modal="showBlockModal = true" @show-report-modal="showReportModal = true"/>
                    </DynamicScrollerItem>
                </template>
            </DynamicScroller>

Here is the code that updates messages:

onMounted(async () => {
    const channels = await streamChatInstance.queryChannels({id: props.stage.id}, [{last_updated: -1}], {
        watch: false,
    });
    streamChatChannel.value = channels[0];
    await streamChatChannel.value.watch();
    messages.value = streamChatChannel.value.state.messageSets[0].messages

    streamChatChannel.value.on('message.new', (event) => {
        scroller.value.scrollToBottom()
        messages.value = streamChatChannel.value.state.messageSets[0].messages
        scroller.value.forceUpdate();

    })

    streamChatChannel.value.on('message.updated', (event) => {
        messages.value = streamChatChannel.value.state.messageSets[0].messages
        scroller.value.forceUpdate();
    })
})
