• 🐞 Bug fix (a non-breaking change that fixes an issue)

📚 Description

The test in

framework/packages/nuxt/src/core/plugins/unctx.ts

Line 17 in 8c2c80e

return Boolean(app?.plugins.find(i => i.src === id) || app.middleware.find(m => m.path === id))

relies on an absolute path. It probably makes sense to resolve plugin paths to absolute when normalizing though, and this resolves the other issue too.
