Descriptions
Mattermost fails to scope the WebSocket response around notified users to a each user separately resulting in the WebSocket broadcasting the information about who was notified about a post to everyone else in the channel.
Mattermost no logra abarcar la respuesta de WebSocket en torno a los usuarios notificados para cada usuario por separado, lo que hace que WebSocket transmita la información sobre quién fue notificado sobre una publicación a todos los demás en el canal.
