Reply all broken in TB 17.02 Rated 4 out of 5 stars

I've been using this add-on for a very long time and it always worked like a charm! So generally: thumbs up!

However, recently, I noticed the Reply-all button does no longer work as expected. When using this button, only contacts which were in the to-field of the original message will get the reply; CC-ed contacts will not.
