Chunk gets completely reset when it has blocks outside of the currently allowed dimension height/size

I was using the caves and cliffs preview pack and my idea was that i can put blocks under the world with the pack then remove it so i have blocks under the world but when i did it i re-joined to the entire chunk got a reset and i know that Minecraft updates don't touch old chunks because of builds. 
I hope this gets fixed because it reset a chunk near my base with a crater  i made so i have a mine.

Thanks for reading this.

does MC-161823 describe your issue?

Reply to @peashooter:

Well, it's kinda describe the issue, but not entirely. General feature of the 2 bug report is about chunk being corrupted when joining the world. But the difference is that while MC-161823 happens randomly, this report happens "when it has blocks outside of the currently allowed dimension height/size". So this report is just related to MC-161823 and not entirely a dupe of it.

For the report, there's not much information about the issue. There're some screenshot but no world file. The report don't update for very long. For the Description, I need you to explain 2 phrases: "caves and cliffs preview pack" and "put blocks under the world".

"Caves and cliffs preview pack": do that means you use data pack?

"Put blocks under the world": this can be mean as "place blocks under the lower build limit", which is impossible in vannila Minecraft.

At this point, what I need you to do is updating the report, explaining those 2 phrases and also give me steps to reproduce and the world file.

Downgrading has never been officially supported. In future, create backups of your world before downgrading them.
