SvelteKit: /_vercel/speed-insights/script.js script is inside the head tag instead of the body tag

[weebao]

I followed the instructions and have my routes/+layout.ts file as below:

import { dev } from "$app/environment";
import { injectAnalytics } from "@vercel/analytics/sveltekit";
import { injectSpeedInsights } from "@vercel/speed-insights/sveltekit";

injectAnalytics({ mode: dev ? "development" : "production" });
injectSpeedInsights();

The description said that I should expect the script to be inside the body tag, but when I checked, it's still in the head tag along with analytics script.
