Fixes incorrect behaviour when using SevenTasks while it is configured to sort tasks manually.

Expected behaviour:

1. Dragging pinned tasks around should update their position correctly and keep that position permanently
2. Dragging items that are NOT tasks should focus the task that is being hovered over for easier drag and drop functionality

Actual behaviour:

1. Dragging pinned tasks around seemingly works, until the task manager is updated in any kind of way, at which point the positions are reverted back to the original state.
2. Dragging items that aren't tasks will only focus the hovered task if previous dragging actions didn't occur between two or more tasks. After that, trying to drag items onto the taskbar will cause the task that was dragged last time to move around according to the mouse's position.
