Describe the bug

When a module contains some specific tagged templates, and it loaded in dev via runner.import, the OXC runtime comes into play and some tags are escaped, probably for safety.

While this might be the correct behaviour, it isn't documented the migration guide, and it can't be turned off.

This breaks Astro rendering, where we sometime render <script> tags.
