I mentioned fullscreen mode because I have multiple widgets only one of which enables full screen mode. That widget, when not in full screen (inline) has the same remounting as the other only inline widgets that use the sendFollowUpMessage.
In the docs it says it should act as a user message so I’m a bit confused about the remounting%253B)
Also just saw another thread on this so might move it there: Involuntary re rendering of widget when using sendFollowUpMessage
