I implemented a workaround for this in Hugo last week, but benchmarks showed that it was a little on the expensive side, so I need to revisit it (make it cheaper).
I have not seen this on any of my sites, so I assumed it was something exotic.
If you use any of the Google Analytics internal Hugo templates, I suspect that is your culprit. If so, you should be able to work around this by copy this (or the other) template into your project, and remove the usage off the __ga_js_set_doNotTrack etc. inline templates.
