The current implementation has a simple memory pressure monitor that starts unloading background tabs when under pressure, to try and prevent the entire browser app from being killed by the system. That implementation is pretty simplistic and can certainly be fine-tuned, but at least it’s not so dumb as to unload a tab as soon as it goes to the background ;)

It would be very helpful if you could provide a bit more context: on what device is that? Did you have other (older) tabs open in the browser when it happened? Other apps running and/or paused in the background? Can you reproduce, and paste the corresponding browser app’s logs?

Thanks!
