This would be better suited for a bug report, but I haven't yet figured out the minimum steps to reproduce the issue.

After running the Slidev dev server for a while, I often see these two warnings and the following error:

runtime-core.esm-bundler.js:51 [Vue warn]: injection "Symbol(router)" not found.

runtime-core.esm-bundler.js:51 [Vue warn]: Unhandled error during execution of setup function 
  at <App>

useNav.ts:276 Uncaught TypeError: Cannot read properties of undefined (reading 'currentRoute')
    at ComputedRefImpl.fn (useNav.ts:276:46)
    at refreshComputed (reactivity.esm-bundler.js:377:28)
    at get value (reactivity.esm-bundler.js:1627:5)

This sometimes happens after adding or removing slides from slides.md. Other times it happens upon first starting the dev server after installing a package.

I'm using @slidev/[email protected] and [email protected].

I don't have any special router setup, I'm using the default theme, and am not calling useRouter myself. Has anyone else run into this?
