Query Pagination block is output when empty

[andersnoren]

Description

The wrapping div of the Query Pagination block is output when there are no previous/next/number links to display in it, which can result in extra margins on the page. It's extra noticeable if the block has a custom block style, like this one with vertical borders:

The screenshot shows a custom theme with a custom block style applied, but it behaves the same in TT1 Blocks without the block style.

Step-by-step reproduction instructions

1. Activate TT1 Blocks.
2. Set the "Blog pages show at most" option in Settings → Reading to a higher number than the number of posts on the site.
3. View the blog and inspect the Query Pagination block.

Expected behaviour

The wrapping div of the Query Pagination block shouldn't be output when empty.

Actual behaviour

The wrapping div is output when the block is empty.

I wasn't able to reproduce but I might be missing something.

View the blog and inspect the Query Pagination block.

How exactly did you create/set up the blog?

It should be fixed via #33635.
