I have the impression that this is caused pure on the client-side.

1. I click on a shape in the SVG node, and the contextmenu appears. Indeed now I arrive on all my breakpoints (in the dashboard's ui.js file) on the server side, and the message is not added to the replayMessage array. So the _ **persistantFrontEndValue** _ parameter seems to do the job well.

2. I switch to another dashboard tabsheet

3. I switch back to the original tabsheet where my svg & contextmenu is located. At that moment I indeed get again a message on the client:

But I didn't arrive on my server-side breakpoints. So it seems that somehow the client replays the messages. I have installed today the dashboard from source code, because I hoped to be able to debug the main.js file. But from the call stack (see above screenshot) I only see minified stuff 🥴

Does anybody have a clue how I could try to find the root cause?  
Because I'm stuck at the moment ...
