MCPE-180350Repeating command blocks in separate chunks sometimes change their update order
Steps to Reproduce:
1. Place two unpowered repeating command blocks a block apart across a chunk border.
2. Insert the following command into the first command block:
/say 1
And in the second command block:
/say 2
3. Place a redstone block in between the two command blocks, powering both at once.
Expected Result:
In chat, 1 and 2 should alternate consistently every tick with no repeats.
Observed Result:
1 or 2 sometimes appears twice, indicating the other command didn't activate that tick.

I'm having trouble reproducing this. It might depend on other circumstances that are difficult to control. How often on average does this occur?
The command blocks in the video change their update order because they are in different chunks (16x16 areas). The game continually randomizes the order in which chunks are updated during a gametick. If the order were not random, then it would have to be directional, which would create other issues.
