Can place blocks 7 meters away in 3rd person mode

Hey there PE fans.
I just found a bug when i played in 3rd person mode.
I tried to place a block 7 meters (7blocks) away from me and it worked.
This is way too far because you can only set blocks in a range of 4 meters in normal mode.

1. Run MCPE
2. Load a world
3. Activate 3rd person mode
4. Place a block about 7 or 6 meters away
