SvelteKit static build query issues

This is reproduction repository. I can't get correct queries if I build with @sveltejs/adapter-static.

procedure for reproducing

create project

npm init svelte@next sveltekit-static-query
cd sveltekit-static-query
pnpm i @sveltejs/adapter-static@next sirv-cli
# and edit src/routes/*.svelte files

launch

# pnpm dev # -> WORKS FINE
# pnpm build && pnpm preview # -> WORKS FINE
pnpm build && pnpm start # -> Does not work properly

1. Start server with pnpm build && pnpm start
2. Access to http://localhost:3000
3. Click ./?key=value (Maybe works properly like fig1 below)
4. RELOAD!! And disappear query value (Does not work properly like fig2 below)

Other links are simple demos.
