The bug
The spawn chunks used to be 16x16 or 16x17 or 17x16 or 17x17 chunks.
Since the recent snapshots the size changed to 23x23 chunks.

How to reproduce
Download
and
Open the "Spawn Chunks Test" World in 1.13.2
Activate and/or deactivate the levers of the clocks of the command blocks
Lower your rendered distance to a minimum
Move away from command blocks and observe the evolution of messages in the chat (If the messages still appear despite being away from a hundred blocks, it is that the chunk is still active. Otherwise, it is not active.)
Repeat the experiment in 1.14+

Spawn chunks being lazy chunks is tracked in another ticket: MC-144610
According to MC-148038, spawn chunks are now 19x19. Can you confirm this?
@unknown Without having tested it, on the other report @unknown mentions that they tested it with the despawning of items and say that the previous spawn chunks where 12x12. So they are talking about entity processing chunks, while this report talks about all ticking chunks (which currently are still 2 chunks wider than entity processing chunks on all sides).
So both reports talk about the same numbers.
19 (entity processing chunks) + 2 (ticking chunks left) + 2 (ticking chunks right) = 23
This is not a bug.
This is a caracteristic of minecraft and how chunks work now.

There is how it works.
