When replying to a topic, if you preview what you have typed, the post you are replying to also contains the text you want to preview, but attributed to the author of the original post. Then, below that, you get your text preview.
For example, if user A has posted message 4 as 'hello' and then user B is replying to that with 'goodbye' when user B does a preview, message 4 will say 'goodbye' (by user A) and the preview box will say 'goodbye' by user B.
This only affects the preview and when the message is saved, all is normal.
