players in gamemode 2 can still have block-breaking animation

If a player in gamemode 0 (survival) starts breaking a block, stops and switches to gamemode 2 (adventure), the player can still produce the block-breaking animation on that block for a short period of time.
This glitch is purely visual and doesn't affect gameplay in any way.

The block also stays cracked if the player in gamemode 2 stops breaking it (as seen in screenshot)
