BUG ct_disable_theme_load when using editorScript with Rank Math

Sandbox

Not available as qsandbox.org uses Wordpress version: 6.4.2, the bug only happens in WP 6.5.2

Bug description

Using the popular SEO tool Rank Math and Oxygen, WP.

WordPress Version: 6.5.2
PHP Version: 8.1.2-1ubuntu2.14
Oxygen (4.8.1)
Oxygen Gutenberg Integration (1.4.4)
Rank Math SEO (1.0.216)

Rank Math includes a Table Of Contents (TOC) block for he Gutennberg editor.

Rank Math has identified the problem at OXYGEN code: plugins/oxygen/component-framework/component-init.php

With the latest Wordpress update, the TOC is not available anymore.

Disabling Oxygen fixes the problem.

With Oxygen enabled I can see that 3 URLs returns a 404 not-found:

Example: https://www.domain_name.com/wp-content/themes/oxygen-is-not-a-theme/home/itwl_pro_001/public_html/wp-content/plugins/seo-by-rank-math/includes/modules/schema/blocks/toc/assets/css/toc.css?ver=6.5.2

It is a virtual URL, removing "wp-content/themes/oxygen-is-not-a-theme/home/itwl_pro_001/public_html/" and using the "/wp-content/plugins/seo-by-rank-math/..." returns the right files.

Example: https://www.domain_name.com/wp-content/plugins/seo-by-rank-math/includes/modules/schema/blocks/toc/assets/css/toc.css?ver=6.5.2

Affected files:

/wp-content/plugins/seo-by-rank-math/includes/modules/schema/blocks/toc/assets/js/index.js
/wp-content/plugins/seo-by-rank-math/includes/modules/schema/blocks/toc/assets/css/toc.css
/wp-content/plugins/seo-by-rank-math/includes/modules/schema/blocks/toc/assets/css/toc_list_style.css

Rank Math has been contacted and they provided the following explanation:

Pratik Deshmukh (https://support.rankmath.com/ticket/your-site-doesnt-include-support-for-the-table-of-contents/#post-783396) Hello, We were able to reproduce this issue on our setup and identified the source of the problem as originating from the Oxygen plugin. In the plugins/oxygen/component-framework/component-init.php file, the plugin has used the template_directory filter, which returns a fake value. Here is the code:
function ct_disable_theme_load( $stylesheet_dir ) {

// disable theme entirely for now
return "fake";

if ( isset( $_GET["has_oxygen_template"] ) && $_GET["has_oxygen_template"] ) {
    return $stylesheet_dir;
}

if ( defined("HAS_OXYGEN_TEMPLATE") && HAS_OXYGEN_TEMPLATE ) {
    return "";
}
else {
    return $stylesheet_dir;
}

}


> // Need to remove for both parent and child themes
`add_filter("template_directory", "ct_disable_theme_load", 1, 1);`
> Due to this code, the path of the block script registered using the editorScript property in the block.json file is being changed to http://rankmath.local/wp-content/themes/oxygen-is-not-a-theme/Local%20Sites/rankmath/app/public/wp-content/plugins/seo-by-rank-math/includes/modules/schema/blocks/toc/assets/js/index.js?ver=1.0.217-beta, resulting in a 404 error. You will also see this error in the browser’s console on your site.
> An example of the editorScript property can be found here: https://github.com/rankmath/seo-by-rank-math/blob/master/includes/modules/schema/blocks/toc/block.json#L9-L10
> 
> I believe this issue is not specific to the Rank Math plugin and could potentially cause problems with all plugins that use block.json to register blocks.
> 
> Please forward this to the Oxygen Builder team so they can take a look at this issue. We will also try to get in touch with them.
> Hope that helps.
