Cocoa pods on chunk borders can break when loading

Cocoa pods attached to jungle logs across a chunk border can break during chunk loading. This happens when the chunk with the cocoa pods is loaded first and there is a delay in loading the chunk with jungle logs. This appears to be the same issue that was patched for several other blocks that attach horizontally in 1.2.0.11--see MCPE-11477.

Steps to reproduce:

1. Place jungle logs along a chunk border.

2. Place cocoa pods on the side of the jungle logs, in the neighboring chunk (by using beans, or with commands).

3. Save & quit while in a chunk on the pod side of the logs, and facing away from the pods and logs.

4. Reload and turn around.

Expected result: The cocoa pods remain attached to the jungle logs.

Actual result: Sometimes the cocoa pods break (they drop beans if drops are enabled). This is more likely when there is loading lag, as when near chunks with a lot of mobs and/or updating blocks.

The attached video

shows this bug being reproduced across several chunks in a small test world by setting random tick to maximum. At the beginning you can see cocoa pods filling 5 rows of jungle logs, and at the end after relog you can see that all of pods from the 4th and 5th rows have broken off.

The attached test world,

, reproduces this bug fairly consistently if you set the random tick speed to 4096 before loading the world. The world contains rows of jungle logs and a system of command block minecarts to automate steps 1-2 en masse. (It also contains some structures relevant to other bugs 😉 )
