Description
Expected behavior
Really cool vanilla feature that is used a lot in mapmaking doesn't seem to work with Paper:
Putting NBT storage inside of a Written/Writable Book makes the NBT storage appear inside the book.
Observed/Actual behavior
Putting NBT storage inside of a Written/Writable Book gives you a blank book.
Steps/models to reproduce
- Run the command: /data modify storage numbers 123 set value '["123"]'
- Run the command: /give @p written_book[written_book_content={title:"",author:"",pages:['{"nbt":"123","storage":"numbers","interpret":true}']}] 1

Research direction
Reproduce the issue with the /data modify storage and /give commands in the report, then trace Paper's written/writable book handling for NBT storage and interpreted pages. Done means the book displays the stored value 123 instead of appearing blank; no source file or test is identified in the report.
