sanitize_post() is not sanitizing Post Object

I wanted to sanitize a WP_Query post object without using foreach.

I used this method:

$  args = array( // ... ) $  data = array();  $  the_query = new WP_Query($  args);  $  data["post"] = $  the_query->posts;  array_map("sanitize_post", $  data["post"]);  return rest_ensure_response($  data);

as you can see that filter is working and its turning to "Display" from "Raw".

But the problem is: <script> tags still standing in post_title field.

Whats the problem?
