Using Dispenser to bone meal a 1-block-high flower will crash the game.

When I attempted to build my flower farm in 1.13.0.6 beta, I experienced a crash of my game. By later tests I found out that simply using a dispenser to dispense a bone meal onto a 1-block-high flower will result in a crash. However, similar issues do NOT effect 2-block-high flowers OR tree saplings.
