Issue Summary

When multiple notifications are sent to a user within the same group in Confluence Data Center, the notifications initially display in the correct order. However, after clicking away and returning to the notification panel, only the most recent notification is visible and the notification history disappears. Despite this, the API retrieves the full notification history correctly. This issue affects the Smart Courses for Confluence app (app key: com.mute.confluence.plugins.lms) and has been reproduced on Confluence versions 8.5.24 and 9.2.7.

Steps to Reproduce

1. Set up two users in Confluence Data Center.
2. User A shares a course multiple times with User B using the Smart Courses for Confluence app, which pushes notifications via the NotificationService from com.atlassian.mywork.service.
3. User B opens the notification panel and observes that all notifications are displayed in the correct order.
4. User B clicks away from the notification panel.
5. User B reopens the notification panel.

Expected Results

All notifications, including the notification history, should be visible each time the notification panel is opened.

Actual Results

• After reopening the notification panel, only the most recent notification is displayed; the previous notification history is missing.

• The API still retrieves the full notification history, but the UI does not display it.

• In some cases, a blank rectangle appears where the "older shares" label should be. Clicking this blank area reveals the share history, indicating the functionality is present but not rendered correctly.

• No relevant error messages are shown in the UI, but screenshots and a video demo have been provided to illustrate the issue.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
