So, Bitcoin ABC (Cash) is three blocks behind the other nodes, but no chain split has been detected. What’s up with that?

Did the block three blocks ago cause a fork? Are we just waiting for someone to mine a Bitcoin Cash block on top of this block and then there’ll be a fork?

EDIT: Here's the log from a Bitcoin ABC node I have running:

Looks like 00000000000000000019f112ec0a9982926f1258cdcc558dd7c3b7e5dc7fa148 AKA block number 478559 was rejected by Bitcoin ABC.

EDIT2: Here's the code [1]. The block was rejected by Bitcoin ABC/Cash because it was smaller than 1 MB.
