Comparison between Discover and `flatpak update` in the terminal

SUMMARY
Whenever the NVIDIA driver gets updated on the host (even when the kernel module is just rebuilt for a kernel update) the NVIDIA driver for Flatpak also needs to be updated. While `flatpak update` on the terminal shows that update correctly Discover shows it as updates for all the installed runtimes, which can be misleading if one is not aware of that quirk.

Fortunately this is just a cosmetic issue, updating via Discover in that state still works, although it ends up showing identical progress for all the runtimes it shows.


STEPS TO REPRODUCE
1. Wait for the NVIDIA driver to get updated on the host
2. Check for updates on Discover
3. Check for updates via `flatpak update`


OBSERVED RESULT
Discover shows updates for all installed runtimes, while `flatpak update` only shows the NVIDIA driver update.


EXPECTED RESULT
Discover should show the same thing as `flatpak update`.
