XML Response wrongly includes <script> tag

Describe the bug

Svelte kit inserts <script async="false" fetchpriority="high"/> in XML responses. using +server.ts

Any kind of tag will lead to this behavior.

This same thing will happen with pretenders on or off or running in dev, tested the latest public version: "@sveltejs/kit": "1.10.0"

But happened in previous versions as well like: "@sveltejs/kit": "1.1.1",
