Using a piston to push a block next/outside world border glitches the block and disables block's outline.
How to reproduce
Teleport to the world border using the following command:
/tp 299999999 256 299999999
Place any block 1 block before the world border
Place piston to push the block to the world border and break the piston afterwards.
You will notice that the block's outline is completely gone even though the block still acts like a block after glitching.
Observations and Expectations
Observations: Block's outline completely disappears after pushing outside world border.
Expectations: It should still appear even after glitching since it stills acts like a block.
Notes: Relates to MC-82010.
