In `get_page_children()`, only check `$page->ancestors` once to avoid duplicates when the function recurses. Adds an argument, `$ancestors`.
Fixes #18962. Built from https://develop.svn.wordpress.org/trunk@30246 git-svn-id: http://core.svn.wordpress.org/trunk@30246 1a063a9b-81f0-0310-95a4-ce76da25c4cd
