When the number of ordinary Arrows held in the off-hand slot is 63 or less, picking up ordinary Arrows (The number of ordinary Arrows picked up in a single instance needs to exceed “64 minus the number of ordinary Arrows held in off-hand”) dropped by a Skeleton/Stray/Bogged causes an inventory/hotbar error: the Arrows in the off-hand slot are replenished, but the remaining Arrows do not appear in the inventory/hotbar. They become invisible, but actually still exist there. These invisible Arrows occupy slots and become unmovable, effectively "locking" those slots. If the drops include not only ordinary Arrows but also Bones/Tipped Arrows, and there's no Bones/Tipped Arrows in your inventory/hotbar, then picking up both types simultaneously will cause both the ordinary Arrows and the Bones/Tipped Arrows to become invisible and unmovable in the inventory/hotbar. The issue is only resolved after performing another interaction (such as opening/closing a door, eating food, or placing a block). Moreover, since you have still not fixed MCPE-227725, I am unable to use the screen recording feature and therefore cannot submit screen recordings.
Steps to reproduce the issue
Hold some ordinary Arrows (less than 63) in your off-hand, then kill some Skeletons/Strays/Boggeds to make them drop ordinary Arrows. Go pick up those ordinary Arrows. Be sure not to pick up any Bones/Tipped Arrows first, and do not have any Bones/Tipped Arrows already in your inventory/hotbar. Then go pick up those ordinary Arrows, or pick up both the ordinary Arrows and Bones/Tipped Arrows at the same time.
Expected result
They should be picked up normally.
Actual result
the ordinary Arrows in the off-hand slot are replenished, but the remaining items do not appear in the inventory/hotbar. They become invisible, but actually still exist there. These invisible items occupy slots and become unmovable, effectively "locking" those slots.
