Hello everyone!
I found out a bit more:
The issue is the window event in my html component being called twice. Also it’s a chrome issue, no idea what has changed around chrome to cause this. Also this only happens when I pass an iframe to the html component. Passing a simple string doesn’t lead to the listener firing twice.
I fixed it by checking the event data to be string (as the second call inserts the [Object object] thing.
If anyone has an explanation I would be happy to hear it.
Best Regards
Alessandra
