Page is not loading correctly when using alternate base dir

[ahaw]

Subject of the issue

Bitwarden doesnt load when using alternate base pathes.
When I set domain to 'example.com/subdir' it loads the page but when the browser is trying to load resources it's ignoring basepath. The url of file is: "testing.test/app/polyfills.c9c57acc9b845fdb9052.js" instead of "testing.test/bitwarden/app/polyfills.c9c57acc9b845fdb9052.js"

Your environment

• Bitwarden_rs version: bitwardenrs/server:alpine
• Install method: docker-compose
• Clients used: Latest chrome and firefox
• Reverse proxy and version: traefik:latest
• Other relevant information:

Steps to reproduce

Use alternate base dir in config and open bitwarden page.

Expected behaviour
