Export button doesn't use project URL

[ghost]

On v9.0.0-rc.43 (and pretty much all previous releases as well), the export button in the collections module sidebar takes the user to /items, without respecting the project URL if it is set in project settings. Perhaps it should prepend the project URL.

Perhaps it should prepend the project URL.

Why should it? The app is served from the API, so it should be safe to assume that the /items endpoint next to /admin exists.

Sorry my mistake this is not related to the project URL.

When serving the app behind a reverse proxy, the app makes all the API calls correctly to the relative path (eg. (domain)/api/...). However, this export request is the only one being made to the absolute path (always (domain)/...).
