In [54352] `update_post_caches()` was replaced by `_prime_post_caches()` to reduce excessive object cache calls. That's because `_prime_post_caches()` checks first if post IDs aren't already cached. Unfortunately this becomes an issue if a post itself is cached but not the meta/terms.
To fix this regression, `_prime_post_caches()` now always calls `update_postmeta_cache()` and `update_object_term_cache()` depending on the arguments passed to it. Both functions internally check whether IDs are already cached so the fix from [54352] remains in place.
