Broken "Back" button
I've launched Gnome Software by clicking a flatpak install link on flathub.org. After that, I wanted to go back to the "normal" view, to check for updates, etc. - however, the "back" button had no effect.
I see the following in the system logs:
Sep 28 12:29:29 dima-dell gnome-software[2125]: gs_shell_go_back: assertion '!g_queue_is_empty (priv->back_entry_stack)' failed
