I don’t see the code on the page at the moment, are you sure you added it correctly? When I tested the code via the console, it was working for me almost all the time.
From the elementor perspective, there is unfortuantely nothing to do about it. It is very situational. In many cases it does work, in other cases it does not. We added code to the plugin to try to resolve these clone related conflicts as much as possible, but unfortunately it is very hard to get around them, if even possible.
I will to some more tests on our local servers to maybe add some improvements if possible for the next release, but I don’t know how much room for improvement is in there.
