 * this has been [fixed in the beta-version](https://github.com/futtta/autoptimize/commit/0a925fa77f9985a875e9e9966eef80bb73942bab)
   and will be in the next version (no eta yet), but if you want you can [download the beta from github](https://github.com/futtta/autoptimize/archive/refs/heads/beta.zip)
   and install instead of 3.0.3 to test 🙂
