Comment:

 The patch is for `get_the_category_list()`, which retrieves the
 `$categories` array via `get_the_category()`.

 `get_the_category()` always returns an array of objects, so if invalid
 data is encountered, it's likely because a plugin or theme did something
 wrong with the `the_category_list`, `get_the_terms`, or
 `wp_get_object_terms` filter, which would be a developer error.

 I don't think we should hide developer errors, a notice seems perfectly
 fine here. Feel free to reopen if you can still reproduce the issue on a
 clean install with no plugins installed and a default theme activated.
