Clone destroys blocks that are dependent on support blocks

This happens with blocks that need other blocks that are under or besides them. Such Blocks are cocoa beans, snow layers, grass, flowers and crops.

If a clone command is executed that clones the support block, the mentioned blocks pop off. For example, place two grass blocks east of the player, place a flower on the furthest one, and run:

/clone ~1 ~ ~ ~1 ~ ~ ~2 ~ ~
