Fixes #32638

Description

There’s a bit of a confusion point in the Query Block with Items per Page. Despite having multiple published posts only one appeared by default. I found the controls in the Block Toolbar to increase but also found it a bit cumbersome to toggle between the Block Toolbar and Block Sidebar to refine the underlying query.

How has this been tested?

• Switch to this PR and run the project
• Create at least 3 post
• Create/edit 4 posts and add query block by typing /query
• Verify query block is showing 3 posts.
