Planel does not use the whole certificate chain

[TobiasP]

I recently installed a new ssl certificate for my domain. I also installed 2 intermediate CA certificates. then I used the "secure panel" function so that the plesk panel uses this new certificate.
When I run a SSL check at http://www.sslshopper.com/ssl-checker.html it says that the certificate chain is broken because only the domain certificate is transmitted but not the intermediate CA. (rootchain.pem file seems not to be used by the plesk panel server)

Plesk 11.5.30 Update #13 on Debian 7.1

Please fix this bug.
