Book merge function has a 50-book limit

[el4ctr0n]

Problem

Dear developers,
I tried to merge more than 300 duplicates of Joseph Conrad's Heart of Darkness and the book merge page only loaded the first 50 books.

Once you scroll past the first 50 books, this is how the merge UI displays books:

Thank you for looking into this bug.

Reproducing the bug

1. Search for a book with lots of duplicates.
2. Select more than 50 books to be merged.
3. Only the first 50 books are loaded and it's impossible to request a merge if there are more than 50 books in the merge list.

• Expected behavior: Being able to merge more than 50 books
• Actual behavior: The book merge function has a 50-book limit.
