I can also confirm this behavior in 1.18.2 Pre-release 1. As an additional note, in my testing, I wasn't able to reproduce this in 1.18.1, so this issue may be exclusive to 1.18.2-pre1, though I could be wrong.

I assume this is a new issue arising from 1.18.2's new structure handling, and isn't referring to the subject of the proposed future change to mob spawning and experience drops mentioned in 1.16's development alongside fixing the hostile-zombified-piglins-dropping-XP-always bug?

What was the actual technical fix?  Does it restrict spawning to only netherbrick within the entire nether fortress bounding box (the entire square of the fortress, default 1.17/1.18 behavior) or does it restrict spawning to only the fortress structure bounding box (the tiny boxs of only the structure).

The latter has the potential to break this farm. https://www.youtube.com/watch?v=ixGwh1pJb9o
