For a couple of days now, Safari "reloads" (or better, "goes back") certain web pages seemingly without a reason.
This happened on different pages for me, but one example where I could reproduce it was App Store Connect.
After logging in, I briefly saw the Overview page and then it snapped back to the Login page. This happened every time, so the page was completely unusable. Similar things happened on Google Cloud Console, where it also snapped back to the start page after I wanted to change something there.
I don't think this is a resource problem, as memory pressure is very low.
My system:
Mac Studio M2 Ultra
macOS Tahoe 26.7 (had this on the previous version as well, and the update did not fix it)
Safari Version 27.0 (21625.1.29.18.28), no extensions
