Issue Summary

When a user opens a watched Trello card directly via the in-app notification sidebar while navigating on a different board/page, newly added comments do not render in the card's activity feed until the page is manually refreshed.

Steps to Reproduce

1)Ensure User B is added as a watcher to a specific card on Board A.
2)Have User B navigate away from Board A to a different board (e.g., Board B) or page.
3)As User A, open the target card on Board A and post a new comment.
4)As User B, open the Notifications menu/sidebar.
5)Click directly on the notification for the new comment to open the card modal.

Expected Results

The card modal opens and immediately displays the latest comment in the card's activity feed.

Actual Results

The card modal opens, but the newly posted comment is missing from the activity feed due to a sync/caching issue.

Workaround

Manually refresh the browser page while on the board to force-reload the latest card comments.
