Switching from weapon to empty hand or vice-versa in Creative Mode while breaking a block desyncs sound and particles from items dropping

Switching from holding a weapon to holding nothing or vice-versa then quickly breaking the block desyncs the sound and particles of breaking and dropping the items.

What I expected to happen was....

Switching fast from one to another would have the effect based on whether I broke the block before or after switching to or from the weapon.

What actually happened was....

Being fast enough on the switch from an empty hand to weapon drops the item but doesn't cause the sound or particles, and switching from a weapon to an empty hand makes the sound and particles, breaks the block for a second without dropping anything but then reappears.

Steps to reproduce:

1. Have something that is not a weapon in your hand
2. Press the Break Block button
3. Quickly switch to something that is a weapon
4. Notice that the block was broken, the items dropped but no sound or particles occurred

1. Have something that is a weapon in your hand
2. Press the Break Block button
3. Quickly switch to something that is not a weapon
4. Notice that the block disappeared while not dropping anything, made the appropriate sound and particles but then reappeared
