I agree with Jark. The user can find the previous taskmanager according to the log link in the history of the attempt.
The reason for adding attempts' information to the timeline is that for some reason, the job failover failed or took a long time. This problem is challenging to locate. As the current timeline is a summary of all attempt information with the attempted timeline, you could find attempts with an abnormal status.
