While the trusted helper should control the lifecycle of the prompt provider suspending an app can't stop the trust session, that simply doesn't work. There are a number of cases where we need the app to be suspended, and the trust prompt provider can be suspended as well, but it the relationship must remain valid. One of those is buying something. If you're in the middle of buying something and someone walks into the room, your screen turns off while you're talking to them, you should be able to turn back on the screen and continue with where you've left off. The fact that the app is suspended in that case shouldn't be visible to the user in anyway.

In some cases, this leaves the dash in a state where the user is unable to interact with it, and the only recourse is to reboot or run "restart unity8-dash" if the Terminal or an adb shell are available. In some cases, this also leaves the app which was in the trusted prompt session, running in the background, and it will not get terminated by the system. To reproduce: 1: Go to the YouTube scope. 2: Scroll to the bottom of the results and tap the "Log-in to YouTube" result entry. 3: When the online-accounts-ui opens up, turn the screen off. 4: Turn the screen back on and notice the login window for YouTube is gone, and the dash cannot be interacted with. So far, I've only been able to do this in the dash, either with the YouTube log-in, or with the app purchasing flow (which is slightly more complex to test). When reproducing this in ubuntu-system-settings-online-accounts, the new account login window goes away, but it is still possible to interact with the system-settings UI, so the user can recover by trying to add the account again, or just quitting system settings.
