baseURL missing for remotely fetched editor styles

Note: I would have created a ticket rather in the Gutenberg repository, but the affected code is in the WordPress core.

When an editor style is added (using add_editor_style) as remote URL (not as path to a file), the editor style definition from get_block_editor_theme_styles() passed to the Gutenberg Block Editor doesn't contain a baseURL field.

Relevant code:

This missing baseURL field prevents the Gutenberg CSS post-processing from rewriting the stylesheet-relative URLs inside the CSS, resulting in broken url(...) references and preview.

When the baseURL is added to remotely fetched styles, too, using the known CSS file URL, the URL rewrite issues are fixed and everything looks correctly:

// [...]
$styles[] = array(
    'css'            => wp_remote_retrieve_body( $response ),
    'baseURL'        => $style, // added
    '__unstableType' => 'theme',
// [...]
