Book on Lectern goes dark in Nether and End

When a Book or Book & Quill is placed on a Lectern in the Nether or End, the book goes dark. I believe that this is an entity lighting issue.

Steps to Reproduce:

1. Place a book/book & quill on a lectern in the Nether or End.

Observed Results:
The book renders darker than expected.

Expected Results:
The book should render brighter.
