<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Ensure that `wp_list_categories()` supports comma-separated lists for 'exclude' and 'exclude_tree'.
<a href="https://core.trac.wordpress.org/changeset/34696">[34696]</a> introduced a regression whereby comma-separated values for 'exclude'
and 'exclude_tree' would be handled improperly when merging the two parameters,
resulting in category IDs being incorrectly dropped from the combined array.
Merges <a href="https://core.trac.wordpress.org/changeset/36005">[36005]</a> to the 4.4 branch.
Props gblsm, hnle.
Fixes <a href="https://core.trac.wordpress.org/ticket/35156">#35156</a>.</pre>
