Renewing access tokens fail when hosting gitlab in subpath

When self-hosting gitlab in a subpath the renewal of personal access tokens fails after update to 18.1.

For this example <domain> is the base domain and <subpath> is the sub path below the domain.

The browser console & access logs shows a 404 error for the following path:

https://<domain>/<subpath>/<subpath>/-/user_settings/personal_access_tokens

The subpath for gitlab appears twice in the url - this means users cannot renew their access tokens.
