Passing a non-empty array will result in wp_prepare_themes_for_js() returning early with that value instead.

$prepared_themes array

An associative array of theme data. Default empty array.

$themes WP_Theme[]|null

An array of theme objects to prepare, if any.

$current_theme string

The active theme slug.
