When Gutenberg is active, block patterns listed in theme.json does not appear

[carolinan]

Description

In theme.json, I have added the following patterns from the pattern directory:
"patterns": [ "site-footer-with-logo-contact-info-social-links-and-copyright", "heading-with-two-font-sizes-and-separators" ]
The version of the theme.json file is 2.
The patterns are in the categories text, columns and headers respectively.

Without Gutenberg active, the patterns show up in the pattern inserter or pattern explorer for these categories.
When I activate Gutenberg, the patterns are not available.

Step-by-step reproduction instructions

1. Install WordPress 6.0
2. Deactivate Gutenberg, if it is active.
3. Add the array of patterns to theme.json of Twenty Twenty-Two or for example Empty theme.
4. In the site editor and block editor respectively, open the block inserter and select the patterns tab. Look under the mentioned categories and confirm that the two patterns are listed. You can also try using the search and search for "footer".
5. Activate Gutenberg and try to find the two patterns. Confirm that they are not listed. There are lots of other patterns listed, but not the patterns you added to theme.json.

I managed to reproduce the issue following the steps provided.

After looking at this, it appear to be a known issue where the WP_REST_Pattern_Directory_Controller wasn't supporting array arguments.

The patterns listed in theme.json were send has an array to the WP_REST_Pattern_Directory_Controller with the slug parameter. Internally the value from the parameter was drop when building the request to the WP.org pattern directory resulting in the listed patterns missing in the editor.

This has been fixed in core in WP 6.0. The change has been backported to gutenberg in #40900 and is available in trunk but not yet released in the Gutenberg plugin distributed in the plugin directory (as far as I can see).

It was released with Gutenberg 13.5.
The issue remains in Gutenberg trunk and Gutenberg 13.6.0.

The PR was merged 7 days ago. I checked the content of lib/compat/wordpress-6.0/class-gutenberg-rest-pattern-directory-controller.php file in tags 13.5.0/13.5.1/13.5.2/13.6.0 and it hasn't change since february 10.

The PR might have been schedule to be included in 13.5 but wasn't merge in time ?

Retested with 14.0.2, and the patterns are listed now.
