group messages from one sender with same subject
I am subscribing to a forum. When someone creates a new topic, a 1st message is received. If someone replies to that topic on the forum, a subsequent message is received, and so on. All messages are from one and the same generic sender, subsequent messages have the subject prefix 'Re: '.
Geary should group these messages. Currently running 3.32.1
In comparison, Gmail web client and Apple Mail on iOS group these messages into one thread.
