I can create a filter to move a matching message to the trash left as unread. So why doesn't the trash folder name in the left column of the webmail show the count of unread messages? Is there a valid reason for this or is it "ticket time" again?

Note another way to illustrate this is simply mark some messages in the trash as unread.

Also, I don't recall if it has always behaved this way. I only stumbled upon it doing some sieve code I was experimenting with when I noticed it (trashing email from obsolete "disposable" email addresses implemented via an alias).
