Steps to reproduce:

- Open the player inventory
- Take an item stack
- Switch the item stack by clicking on another item stack

The hand item will remain in the slot from where you took the first item stack. I would expect, that the hand icon switches to the new slot.

It works as expected if you switch the item stack in your hand via the quickbar.

Clicking on an item while holding another item is how you swap items. It doesn't matter if there is a hand slot reserved or what inventory the new item is inside. What you did was exchange the cursor item and the slot you clicked on. After swapping, if you clear the cursor the new item will be returned to the hand position, which happens to be where you picked up the first item.

The behavior you are expecting is easily had by pressing Q (clear cursor) before clicking on the new item to pick it up.
