Users are unable to re-order subtasks from the parent view, within the child panel while "Hide done" is disabled

Attempting to drag-and-drop sub-tasks in the issue view or sub-task list displays the expected drag handle and animation, but dropping the item does not change its position. The order of sub-tasks remains unchanged after the interaction.

Reproduction Steps

1. Open a work item with child work items
2. Attempt to re-rank a work item by dragging it on the middle of the target work item
3. It should show an edge (the blue line) but re-ranking fails

Expected Result

• The dragged sub-task is moved to the new position in the list.

• The new order is persisted and reflected for all users viewing the issue.

Actual Result

• Drag-and-drop interaction appears to work visually while dragging.

• When the user drops the sub-task, the list snaps back to the previous order.

• No change in sub-task ordering is saved.

Impact

• Users cannot control the execution order of sub-tasks

• Causes confusion because drag handles are visible and suggest reordering is possible.
