Small misalignment still present on the document picker on Page Tree macro

Steps to reproduce

1. Edit a page with CKEditor
2. Insert Page Tree macro from CKEditor toolbar or from Quick Actions
3. Under "Optional parameters" tab (first tab), 'Open to' section, observe the alignment of the document picker at the point where the picker and the type of resource drop-down (from the right side) meet

Expected results

The picker is aligned.

Actual results

The picker is still a bit misaligned on the bottom when selecting the following resource types: Document, All attachments, Attachment, All translations, All objects, but is aligned when selecting types of resources that don't have pickers, like: Farm, Wiki, Space, Objects of type.

It is to be mentioned that the misalignment reproduces only on "Open to" section, but not also on the "Root" section above it.

The issue couldn't be reproduced on XWiki 18.0.0.
