/clone command can clone more than 655360 blocks, exceeding the limit

Summary:
Since 1.18, the limit of /clone command in the bedrock edition is 655360 blocks.
However, the command can clone more than 655360 blocks successfully.

Steps to reproduce:

1. Create a new world. Set a larger simulation distance to avoid the error "cannot place blocks outside the world".
2. Run /clone -32 -64 -64 -1 256 -1 0 -64 0
3. Wait until the command execution finishes.

Observed results:
The command executed successfully, cloning 657408 blocks. (over 655360)

Expected results:
The command fails and throws an error.

Note: This is NOT a duplicate of MCPE-183515, because the limit is 655360 blocks, not 32768 blocks. MCPE-183515 describes an expected behavior, and it should be closed.
