Version

Steps to reproduce

When using watchQuery, the watchers are not triggered when internally redirecting to an URL with trailing slash and without query string parameter set (eg to /query/)

1. Clone the linked repo
2. Install nuxt-edge (npm i)
3. Run dev mode (npm run dev)
4. Click on the links and push "forward"/"backward". Look at the URL and the received data.

What is expected ?

watchQuery watches as usual and calls async functions correctly.

What is actually happening?

watchQuery does not listen.
