Infinite redirection when using qs after nuxt 3.11

[Rigo-m]

Environment

Netlify, various nuxt versions, check repo

Reproduction

https://github.com/Rigo-m/test-query-netlify

Describe the bug

Up until nuxt 3.10, integration with qs (which is needed for deep objects handling in query, e.g.: handling instantsearch filters state) works flawlessly in netlify.
From 3.11 onwards, there is an infinite redirection happening when the query values contains spaces.
I think this is happening because %20 gets transformed to + which gets re-transformed to %20 by qs, but I'm not sure.
I'm also not sure if this is an upstream issue with nitro (paging @pi0 )

Here relevant netlify links:

Nuxt 3.11.2 with qs in router-options
