Similar to MC-53434 and MC-63578
Issues:
It is possible to place blocks outside of the world border using full blocks that are inside the world border (attachment below)
Expected:
Blocks shouldn't be placed out of the world border...
Note: Blocks can only be placed out of the world border if they are adjacent to a block inside the border, meaning the player can only place 1 block out into the border.

@tryashtar Thanks for making that note - I updated the title so it's hopefully somewhat more understandable 🙂
Can confirm in 1.16.5 and 21w18a.
Can confirm this behavior in 1.17.1 and 1.18 Pre-release 2.
Confirmed, note this is referring to when you're already outside the border and are placing blocks against it from the outside
