Changing language unmounts the component tree

[ChezFre]

Description

When the language is updated via router.replace(pathname, { locale }) or the Link locale prop as described in the docs the component tree gets remounted. This causes every child component to reset its internal state.

Reproduction description

Steps to reproduce:

1. Click on the count button to increase the local state of the client component
2. Click on the navigation link of the inactive page
3. Notice that the count value has remained the same
4. Click on the language button or link of the inactive language
5. Notice that the count has reset to 0

Expected behaviour

Changing the language should not unmount the component tree.
