Description

The browser sync script file fails to load when an APP_BASE_HREF is used. What is the rationale behind of removing the leading slash of the script path here? If I comment out this line, it works!

🔬Minimal Reproduction

Create a project with CLI, add SSR support and replace this server.get('*' in the server.ts file with server.use('/path'. You need to set the APP_BASE_HREF for the browser to the same value /path.
