Unable to delete all tags from a component

After adding one or more tags to a component, I'm unable to delete all of the tags from the component. I can add, delete, and change tags. However, I can't delete the last tag from the component. I've tried from the Cachet web interface as well as via the Python cachet-client package. I'm running Cachet 2.4.1 on Ubuntu 24.04.1 LTS (x86).
