Lots of TNT + Low render distance removing a chunk + bedrock

On a flat world, if you do /fill ~ ~ ~ ~19 ~19 ~19 tnt to create a 20x20x20 cube of TNT, then light it, and have the lowest render distance possible, a whole chunk + bedrock not loaded could be removed.

I'm not sure if it can be performed multiple times, but it happened to me and my friend.

 

I don't have any proof, but yes, this really happened.
