CORS error when navigating to components functionality with CORS Disabled??? (Docker-compose installation with default docker-compose.yml)

Dear,

we recently started with the installation of dependencytrack with the use of docker and docker compose
I noticed that cors is default enabled on the components functionality.
Even do we did not explicitly set cors with any environment setting.

I configured the docker compose file with the default information from the website
only adjusted the
**API_BASE_URL=http://bcco-sca01.domain.local:8081**
on the front end part


IF i navigate to the components page i get an cors error
