I have not yet checked to confirm that this is present in the actual HTML source (Ctrl+U). Certainly it’s present in the source shown by inspect element, but that’s the browser’s interpretation of the source, as amended by any extensions (or by on-page javascript). Still, I cannot think of any extensions I may be running which would have this effect. I use pretty much stock Firefox, to which I have only recently added Privacy Badger and uBlock Origin. Next time I see this (and I don’t doubt that I’ll see it again), I’ll check.

My suspicion is that this is some interaction of the URL-building code and a caching layer. If it adds a parameter, and then that gets cached, so it adds it again, and so ad infinitum. But that’s only a suspicion.

This isn’t a bug I’m experiencing myself. It’s one I’ve seen intermittently on a lot of different WordPress blogs in my general browsing of the internet. Doubtless I’ll continue to see it. Next time I’ll take a copy of the full page HTML or something.

I am not using WordPress at all myself. This is something I’ve come across several times simply browsing the net, on a bunch of different websites. Most recently https://www.lunarmobiscuit.com but also https://captainawkward.com and many others. As I said, it’s intermittent.
