Breaking double tall grass gives incorrect particles

Confirmed on Samsung Galaxy Note 3. Android 5.0
Only works if broken on bottom block of double tall grass

This bug was partially fixed in build 14, but still the top particles are the peony particles

When breaking peonies, the top part has tall grass particles.

This is still there in 0.11.0 alpha. The top has the peony particles while breaking it.

The particles are no longer unshaded.

Please reopen. This Affects 0.12.1. Tall grass top layer when broken now shows sunflower particles.

Steps to duplicate
-Break tall grass that generated naturally after creating your world.
When breaking the tall grass the top layer of the grass will show sunflower particles.

The particles are different now so there is a new ticket open for it.
