<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Fix termmeta pre-fetching in `wp_get_object_terms()`.
<a href="https://core.trac.wordpress.org/changeset/34529">[34529]</a> introduced logic intended to prime the termmeta cache for certain
values of the `fields` parameter. There were a few bugs:
* The `all_with_object_id` param was misspelled.
* `term_id` was used instead of `ids`.
* The values being passed to `update_termmeta_cache()` in the case where `fields=ids` was not correct.
All of these would result in a failure to pre-fetch termmeta in some cases.
Props dlh.
Fixes <a href="https://core.trac.wordpress.org/ticket/36932">#36932</a>.</pre>
