This is something they actually worked on. In all of the new missions (from LoR onwards) the dialogue doesn't break the cloak. I don't know if or when are they planning to implement those changes to the older content, but I'm fairly certain that all new content that will come will consider this and don't let dialogue drop us out of cloak.
This. For everything else most of us are just used to cloaking AFTER the dialogue because by the time this gets fixed we'll be as old as Leonard Nimoy and William Shatner are now.
We can tell our great grandchildren, "In my day, our cloaks were so sensitive that even dialogue broke them and we couldn't change our clothes!"
