Issue description: I created a pattern that is empty except the top layer which was a pattern of some concrete. Every time I attempt to use impose to place the pattern the game crashes. However, the server which I am playing on correctly imposes the pattern onto the block that I have selected (tested in single player as well, the pattern is still correctly imposed).
(After some testing it seems this only happens when in survival mode - placement works fine in creative)
Edit: Forgot to mention the crash is client-side only (server continued to run fine)

Steps to reproduce:

• Create pattern that is mostly empty
• Attempt to impose the pattern onto a block

Crash Log:
crash-2022-04-12_11.14.19-client.txt

Screenshot of setup (left to right): block attempting to impose on (deepslate bricks), pattern to impose (combination of red & white concrete), and result after imposing pattern (after reloading from crash).

Reproduced. Will fix.

Fixed in 1.2.84
