Search projets by tags in WebGUI

If I am to believe https://docs.sonarqube.org/latest/project-administration/project-settings/ it should be possible to add tags to a project and filter my projects based on tags on the projects-page.

Expected behavior

Given: I added tag < tag-name> to a project
And: I am on the projects page
When: I enter < tag-name> in any of the search-bars.
Then: I should see the project tagged with < tag-name>

Actual behavior

Given: I added tag < tag-name> to a project
And: I am on the projects page
When: I enter < tag-name> in any of the search-bars.
Then: I do not see any projects
