Undo-Deleted realtime notification receiving Edited DateTime value even though the message has not been edited.

Question

In following scenario we are receiving EditedDateTime value even though message has not been edited.

1. Subscribe Ms-Teams subscription https://graph.microsoft.com/v1.0/subscriptions with chat resource. e.g https://learn.microsoft.com/en-us/graph/api/subscription-post-subscriptions?view=graph-rest-1.0&tabs=http
2. Send message from one of the Team or Chat Item. {Do it from https://teams.microsoft.com/_#/ browser}
3. Receive the notification with createdDateTime value but lastEditedDateTime and deletedDateTime are null respectively.
4. Delete the message from {https://teams.microsoft.com/_#/ browser}
5. Receive the notification with createdDateTime and deletedDateTime with value but lastEditedDateTime value is null.
6. Undo delete action from {https://teams.microsoft.com/_#/ browser}
7. Receive the notification with createdDateTime and lastEditedDateTime with value but deletedDateTime value is null.
8. Looks not correct because original message was not edited any time.

When I called a https://graph.microsoft.com/beta/teams/<TeamID>/channels/<ChannelId>/messages?$top=1 from Postman
I got the correct details. Receive the data createdDateTime with value but lastEditedDateTime and deletedDateTime are null respectively.

In real-time notification, we are getting incorrect data. I have attached snapshot for more information.

The cause is we are not able to understand whether the message was actually edited or undo deleted.
