What happened?

• I opened Monal and sent a message to a channel
• The channel was out-of-date and had over a week's worth of messages pending delivery.
• All the old messages were loaded, and are shown beneath my new message.
• My just-sent message is now show in the conversation completely out of chronological order; it's show before all the messages for the last weeks.

Anything else?

XEP-0357 is shown in red. I don't believe that this is relevant. All others are supported (purple).
