Deck comments with mentions are sent twice to NC Client, three times if there is a reply to a comment with a mention

Steps to reproduce

0. Install NC client and log in as userB in one computer and log in as UserB on another with the NC client synced
1. Activate email reminders every 3h
2. Create a Deck card as UserA
3. Share board and cardX with UserB
4. Make a comment as UserA on the card mentioning @UserB (5th of July)
5. UserB receives a double notification on his NC client
6. The day after, UserB replies to UserA's comment containing the mention @UserB (6th of July)
7. @UserB receives three notifications on his NC client

Expected behaviour

UserB should receive 1 notification in the first case an none in the second.

Actual behavior

UserB gets 2 notifications when he is mentioned and 3 to himself when he replies to a comment when he is mentioned

Additional info
Screenshots - NC client main window and Settings.

Now that I am watching the double notifications, it may be the fact that a comment with a mention and the same as created comment are not recognized as pertaining to the same comment and thus two notifications are sent (but maybe it is what is espected?). But the second screenshot, where the three notifications are sent is more surprising because they are identical messages.

Below I also paste my present notifications settings, in case it helps.

Two notifications

Three notifications
The tree are identical this time and the case is the one above
UserB replies to UserA's comment containing the mention @userb and gets three notifications from himself.

Notifications settings

Start with the numbered Deck comment and mention reproduction steps, using the listed Nextcloud 24.0.7 and Deck 1.7.3 setup as context. No source file, test, or entry point is named, so trace how a mentioned comment and its reply generate notifications; done means one notification for the first mention and none for the self-reply case.
