### **Summary**  
Task Manager: Unexpected behavior when moving non-active icons in Wayland
session with manual sorting.

---

### **Description**

#### Steps to Reproduce  
1. Ensure you are using KDE Neon under a Wayland session.  
2. Set the Task Manager to manual sorting mode.  
3. Open multiple windows of various applications, ensuring they appear as
separate icons (disable grouping).  
4. Perform the following sequence:  
   - Select an icon representing an inactive application. Drag it to a new
position in the task manager and release the mouse button.  
   - Immediately afterward, select a neighboring icon (without activating its
associated application) and begin dragging it to a new position.  

#### Observed Result  
- While dragging the second icon, before releasing the mouse button:  
  - The icon you are dragging suddenly resets to its original position.  
  - The neighboring icon that your cursor first hovered over becomes "attached
to your cursor" and starts moving instead.  
- This behavior consistently disrupts attempts to rearrange icons unless
specific steps are taken to avoid it.  

For example:  
- If you have three distinct icons for the same app (not grouped) and drag the
third (rightmost) icon to the left in the first position, this initial move
succeeds.  
- However, if you then immediately try to drag the middle icon to a new
position, let's say to the right:  
  - The icon you try to move (middle one) resets to its original position.  
  - The third (rightmost) icon unexpectedly becomes the one being moved, even
though it wasn’t selected.

#### Expected Result  
- The icon being dragged should remain selected and move to the intended
position without interference.  
- Other icons should not reset or attach themselves to the cursor unexpectedly.

#### Workaround  
- Click the icon first to activate its associated application, then drag it.
This extra step prevents the erratic behavior and allows rearrangement.
