[Users] Replies appear as unread in ignored thread

[Removed after GDPR request]

Hi,

I notice something strange on one specific list:

http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-dev

1. I mark a thread as ignored (right clicking on its
very first message)

2. When a reply to that thread is posted it appears in
CM as unread rather than being ignored too. (check
attached screenshot - the message after the selected
one).

I have seen this happen only in this list and in more
than one thread. The only filter which applies to this
list just moves the message to a folder:

Condition: header "List-Id" matchcase "cfe-dev.lists.llvm.org" | to_or_cc matchcase "cfe-dev at lists.llvm.org"

Action: move "#mh/Mailbox/cfe-dev"

I have no filters which would explicitly mark a
message as unread.

Has this anything to do with CM or is it a bug of the
list?

version 3.17.0git181
