It's the downside of using 'lazy' rewrite rules.

Your rules basically say "rewrite everything that isn't a file or a directory to index.php".
Which means that every typo or missing asset will generate a second request of index.php.

Store your assets in a separate /assets folder, and exclude that from rewriting to avoid issues like this.
