Odd crash with dispensers and bonemeal

In the Bedrock edition of Minecraft for Windows 10, I have found an odd bug. It seems that when I power a dispenser containing bonemeal underneath of a grass block, the game crashes. I do not know if this bug also occurs on other platforms. I have tested the bug for a while, and I am fairly sure that (although odd) this is the cause of the crash. The screenshot attached was taken shortly before the game crashed.
