Version

2.7.8

Reproduction link

github.com/jonaskuske/vue2-asset-base-repro

Steps to reproduce

• Run npm i to install dependencies
• Run npm run dev to start the Vite dev server
• Visit localhost:5179
• Observe that the request for javascript.svg fails because the URL is broken

What is expected?

The image src is transformed to a valid URL (http://locahost:5173/...)

What is actually happening?

Since all parts are passed to path.join, the URL breaks as one slash is stripped from the protocol (http:/localhost:5173/...)

This is fixed in the v3 version of compiler-sfc, submitted a PR that applies the same behavior to v2 :)
