To recreate:

1) set down chest, barrel, enderchest or shulker box
2) using a controller, rapidly try to fill the small chest inventory from player inventory using double click method (items or stacks do not matter)

Expected result:
Every item in player inventory enters container inventory in sequence, cursor focus follows player selection in player inventory.

Current result:
upon moving item into the 3rd or forth container slot, player cursor focus will jump to slot one in container inventory and player will mis-click, sending whatever is in container slot one back into player inventory. Highly frustrating and easily recreated.

Additional: this focus stealing also happens if trying to double click items from container back into player inventory - container slot 1 will steal focus after the 3rd or 4th group/item moved.

I have only observed this behavior using a controller. Release 1.19.73 does not exhibit this behavior
