Query loop ignores items per page setting for sticky posts

[alaczek]

Description

The query loop block displays all sticky posts, regardless of "Items per page"settings.

Step-by-step reproduction instructions

1. Add four posts to a site, make two of them sticky.
2. Add two query loop blocks to a front page or home template.
3. Configure the first query loop:

• items per page: 1
• offset: 0
• max pages to show: 1
• inherit query from template: disabled
• sticky posts: include

4. Configure the second query loop:

• items per page: 1
• offset: 1
• max pages to show: 1
• inherit query from template: disabled
• sticky posts: include

5. Notice the editor shows the right posts/number of posts.
6. Save and preview the site. Both loops will display the two sticky posts.

I expected both query loops to display one post only, and it seems they both show all the sticky posts instead.
I'm wondering if this is the expected behavior of sticky posts in a query loop, because excluding sticky posts does fix the issue. If this is expected, how can we clarify that "Items per page" setting doesn't apply to sticky posts?
