Comment 5 for bug 1481049

Confirmed on Ubuntu 17.10. The Files 3.28 Flatpak has this bug fixed by calling the Type of ISOs 'Other' and you can get more info on the Types with the 'Type (Detailed)' column. Ubuntu 18.04 is shipping with Files 3.26, however, so this bug still applies to Ubuntu.

I filed a bug upstream here but immediately closed it when I realized that the new behavior is intended and makes sense: https://gitlab.gnome.org/GNOME/nautilus/issues/356

On Ubuntu 17.10 or 18.04:

```
sudo apt install flatpak
flatpak remote-add --from gnome-apps-nightly https://sdk.gnome.org/gnome-apps-nightly.flatpakrepo
flatpak install gnome-apps-nightly org.gnome.Nautilus/x86_64/master
nautilus --quit
flatpak run org.gnome.Nautilus
```
