Tall Grass Texture Glitch

What I expected to happen was: *
To break double tall grass and not see for a split second a flower.

What actually happened was: *
It showed me the top half of a 2 block high flower (can't remeber the name of the flower, but it's white.)

Steps to Reproduce: *
1. Find some double tall grass
2. Break the BOTTOM half of it
3. If you don't see the flower for half a second, then retry processes from step 1.
4. observe the Bug
