Some info in your report seems to be missing; how is that darkness created? Custom dimension type?

@@unknown, description updated.

I couldn't replicate in 26.1 snapshot 5 with carpets and with block entities it is not working because of this bug: MC-305999

@Maximus_3069
I can still reproduce it in the 26.1 Snapshot 5.
