Up until last month, if I opened owner + profiles A, B and C, in this order, profile A would go BFU even though it had background permission. If I opened profile A, profile B would go to BFU.
For a while now, profiles that have "running in background" permission will remain in AFU and profiles without it will go to BFU after they're kicked out of the "3 open profiles" set.
While I actually prefer the new behavior, I don't remember having read anything about this in the release notes. Could it be an upstream change? Or a side effect of the changes GOS has made to Private Space behavior?
Unfortunately I cannot pinpoint which release brought these changes. I'm almost sure it's a November 2024 release, not anything sooner.
