Please describe the bug

Adaptive cards are being sorted according to the time stamp in the activity, if the scroll of the chat is in the middle of the chat while the reorder happens, it will announce as new message ,

this is a problem when one of the adaptive cards contains a set of suggested actions, because once the ordering happens , the suggested actions dissapear.

this was reported by a customer by scrolling up and down multiple times.

Do you see any errors in console log?

No response

How to reproduce the issue?

1.- use a PVA bot which send at least 3 messages , one after other , the last message should contain a set of suggested actions
2.- start the chat, and wait for the suggested actions to show up
3.- scroll up and down
4.- once the suggested actions dissapear corroborate the order of the messages

this is not an easy bug to reproduce, since the re-order doesnt always happen,

What is the expected and actual behavior?

to do not throw a new message notification under the scenario described

Start with the reported PVA bot reproduction steps and observe message reordering while scrolling, including the notification and suggested-actions behavior. The issue is resolved when reordering does not announce an existing message as new and the suggested actions remain available in the correct message order.
