Comment:

 It's still an issue, though, as core should be more resilient to how
 plugins are filtering the post object being inserted. I'm assuming this is
 due to the plugin filtering `"rest_pre_insert_{$this->post_type}"`. It's
 clear that this is also closely related to code quality which would have
 been identified by implementing PHPStan static analysis (see #64898), as I
 can see many issues where assumptions are made about what types will be in
 `WP_REST_Posts_Controller`. So I'll make some type improvements and look
 at bypassing the unique slug check when there is no ID.
