We're shipping with an earlier built-in Svelte version to support the most number of people out of the box. If you want prettier working correctly, install the latest version of prettier and prettier-plugin-svelte inside your project, then it will format correctly because the Svelte 5 parser will then be used which understand this syntax.

Make sure you have a .prettierrc file added as well!
