Router (goto, invalidate etc.) not working in production

[pixelmund]

Describe the bug

I noticed that the router (goto, invalidate etc.) doesn't seems to me work, upon reaching a reasonable size.
The singletons module gets bundled inside vendor.js and so the router is set to undefined before the init function is invoked.

/// vendor-c70aba79.js
let router$1;
function init(opts) {
  router$1 = opts.router;
}
/// ....
const router = router$1;
const goto = goto_;
const invalidate = invalidate_;
async function goto_(href, opts) {
  return router.goto(href, opts, []);
}

vendor-c70aba79.js:1117 Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'goto') at goto_ (vendor-c70aba79.js:1117) at HTMLButtonElement.click_handler (index.svelte-8e9d7a38.js:401)
