Changeset 39236 for trunk/tests/phpunit/data/themedir1/page-templates/38766/trailing-comma-post-types.php

Posts, Post Types: Improve sanitisation of templates' post types.

Prevents post type templates ignoring post types due to invalid characters. Each entry in the Template Post Type comment is run through sanitize_key() to match the sanitisation used by register_post_type().

Fixes #38766.
