Stuff like this is why I consider uBlock Origin to be the bare minimum security software for going on the web. The amount of 3rd party scripts running on most pages, constantly leaking data to everybody listening, is just mind boggling.
It's treating a symptom rather than a disease, but what else can we do?
I also have taken to using adguard home on the router. It blocks 15 or 20 percent of all my traffic. It's quite scary how bad the tracking and other nasties has become.
