+/**
+ * Disable Child Theme (if Safe Mode is active)
+ *
+ * The `is_child_theme()` function returns TRUE if a child theme is active. Parent theme info can be gathered from
+ * the child theme's settings, so in the case of an active child theme we can capture the parent theme's info and
+ * temporarily push the parent theme as active (similar to how WP lets the user preview a theme before activation).
+ *
+ * @since 3.20
+ * @since 3.23 Moved from `ET_Core_SupportCenter::maybe_disable_child_theme()` for an improved Safe Mode experience.
+ *
+ * @param $current_theme
