system_certmanager.php: HTML tags in certificate description drop-down
If you navigate to the Certificate Manager via the User Manager to add a certificate to a user, and select choose an existing certificate you are presented with a drop-down of existing certificates to choose from.
That list displays <i>In Use</i> if the certificate is in use.
HTML tags not allowed in selector option values
