Issue/Introduction

In the Modern User Experience (MUX), users are unable to delete a predecessor task from the Timeline view if a filter is applied. The deletion fails to process, leaving the task in place without surfacing a UI error message to the end-user. Reviewing the browser developer console reveals an error indicating that an "external dependency" is undefined.

This issue displays inconsistent behavior across different views:

Timeline/Gantt View: Deletion fails silently while a filter is applied. Removing the filter allows the deletion to succeed.

Grid View: Deleting the exact same filtered task works perfectly fine without any issues.

Steps to Reproduce:

1. Log into Clarity and open a project in the Modern User Experience (MUX).
2. Create two tasks within the project.
3. Establish a predecessor/successor dependency relationship between the two tasks.
4. Switch over to the Timeline View.
5. Apply a filter to isolate the predecessor task.
6. Right-click on the filtered predecessor task and select delete.
7. Observe that the task remains in place and no toast or UI error message is displayed.
8. Clear the filter and attempt the deletion from grid/timeline view and observe it is deleted.

Expected Results: Behavior to be consisted across grid and timeline view. If a system failure does occur, it should gracefully surface a meaningful error message to the user rather than failing silently.

Actual Results: The task deletion silently fails in the Timeline view while a filter is applied.
