Saving Drafts with Roundcube marks old Mails in INBOX as unread.

Hello List,


I have a problem with the client Roundcube. Whenever I save a draft to the Folder INBOX.Drafts a old mail in my INBOX will be marked as unread.

Here are the IMAP Logs from Roundcube and Dovecot debug logs. I have no idea why it happens. The IMAP protocol looks normal to me but as you can see in the second to last line in the Dovecot log Dovecot is changing the flag of an old E-Mail in INBOX that has the same UID as the Mail that was just created in INBOX.Drafts.
