Describe the bug
Messages are cloned from the other convo, despite what convo I'm in, switching between them will see this

models: wizard coder & mistral

Root cause:
Known issue, message id could be duplicated (since we use unix timestamp as id), it sends twice when pressing enter with Vietnamese message (ascii characters some how repeating the send action) -> DOM elements in list rendering with duplicate keys
