Wrong weather details in notification panel
I'm not sure this has to do with GNOME Weather or GNOME Shell itself, but after resuming from sleep the temperatures in the weather widget in the notifications panel do not correspond to what GNOME Weather shows when you open it. The units are definitely the same, and the weather details change over time in the widget, but they're never the same as in GNOME Weather after waking up. This even sporadically persists across reboots.
Curiously, I noticed that the correct information shows up for a split second (after login) before getting overwritten. I was able to see this through a panel indicator weather extension I'm developing that pulls its info from the notification panel's weather widget. I even thought my extension might be causing this, but even uninstalling it doesn't change this behaviour. In case someone wants to double check its code, here's the git repo.
This is on a fresh Arch install with GNOME 43.2. Can't test other distros/flatpak atm.
