Transferring items to Certain Containers is Buggy

[Mojang] Mega_Spud (Jay Wells) Update:
In 0.16.0 on touchscreen, this seems to affect all containers including chests.

Tested on Samsung TabPro SM-T520 in Creative mode

When transferring a stack of items to a Hopper, dropper or dispenser, the items don't reliably move to the container.

Examples

• If trying to transfer half a stack of arrows to a dispenser, when you release halfway through holding the item, the progress bar continues animating until fully green, but nothing actually moves to the container

• When holding the item to transfer a whole stack, only some of the items transfer, or none at all.

• Tapping a stack will transfer one item, but double tapping will fill the transfer bar, but none will move across. (the transfer bar then doesn't disappear)

• When holding a stack to transfer it, the transfer bar can move around following finger movements, and will then sit out of place (see screenshot #2)
