Page searched by its exact name is not found in a page picker for a macro parameter when its subtree is larger than 10 pages

How to reproduce:

• create a tree of pages, with a root, 2 children and then 2 more children in one of the roots - 5 pages in total
• use a macro that has a parameter of type DocumentReference - in my case I used the tagged pages macro from contrib
• in the parameter input, type the exact name of the top level page
• result:

the page is found, as the first result

• add 7 more pages in one of the children
• do the same search in the document reference parameter, for the exact name of the top level page

Expected result:

• the top level page is still found when searching for its exact name

Actual result:

• the page is not found anymore, nor as the first result nor lower in the list
