Replies that are an "action" don't show the source message
If a reply is an "action" like "/me", the source message is not visible.
See Neochat vs Element:
Neochat (above) shows just "Carl Schwan hides" without the original message, making it hard to understand that it's in fact a quote and not a separate message. Whereas Element (below) shows correctly both Carls reaction and the original message.
