Block Editor: Unable to select a parent page on a site that has lots of pages

[rambogenius]

Steps to reproduce

1. Starting at URL: https://prestonhistory.com/ (user's site with 400 plus pages)
2. You can try to edit any page and try to find Subjects page to set as its parent page in Page attributes, it cannot be done in Block Editor as it never comes up in search. So user as to rely on WP-Admin Dashboard to make this change
3. It does not happen on sites with less number of pages though

What I expected

User should get exact match appeared first in a search so that user can easily select a parent page

What happened instead

The page name never comes up in search when the pages are higher on a site

Might be fixed with this commit WordPress/gutenberg@77fbd6f

Needs re-testing once wpcom is on Gutenberg 9.3.0

Simple site

User's objective was to use parent-child feature for arranging menu. Guided them to use the menu editor instead, for the moment.

Current workaround is to go to Pages via WP Admin and then use "Quick Edit".

Informed them about WP-Admin workaround.
It looks like this thread is possibly related to #30252

Gutenberg 9.3 with potential fix is on WordPress.com already — is this still an issue? cc @Automattic/good-mountain

I tested and was able to view and search the parent page selector for the site mentioned. I'll close as I believe this has been fixed. Please reopen if there are more report.

Reopening this issue as we have another report in this forums thread: https://wordpress.com/forums/topic/lovecraft-cant-add-pages-after-parent-page/

Logged in as the user and confirmed the same behavior as the OP. They have 175 Pages published.

Advised to use the wp-admin workaround for now.

This looks like a duplicate of this report: #49684

Since this report contains user-specific data, I'm closing it in favor of #49684 , which we'll try to get some eyes on!
