Vue app context not the same when hydrating at client side.

• [x] I have read the troubleshooting section before opening an issue.
• [x] I have tried upgrading iles and vite.

Description 📖

I was trying to use vue-i18n with client:load hydration, I cannot get it work because it keeps telling me i18n is not installed to the app.

So I tried to print out getCurrentInstance() within the component, it turns out that at each component rendering (there is a list of them), instance.appContext.app is different, its uid is never 0 (which is the one from app.ts). . Was I doing something wrong? Or is this intended?

Reproduction 🐞

print out getCurrentInstance() in any client hydrated component.

This is expected, as the "outer app" will not be available when the app is built.

During development, the entire site is a Vue app to support HMR. Anything outside islands will be static at build time.

Vue apps can't have multiple mounting targets, so each island will be mounted as a Vue app on its own.
