The app do not always automatically forward from feedback

[SandGrainOne]

Description

The app is supposed to automatically refresh/reload/forward the user to the next page if the current process step of the instance change. This isn't always the case.

One case where this does not work properly is if the order of steps are data->feedback->confirmation. The feedback page is displayed, but changing the current step from feedback to confirmation does not trigger automatic refresh.

To Reproduce

Requires an app with process steps in the order data->feedback->confirmation.

1. Start the app, fill in the form and click next.
2. Observe that the feedback page is displayed.
3. Call the process/next endpoint as application owner to move the process one step.
4. Observe that the feedback page now has stopped polling for the instance process information, but nothing happens.
5. The user is not forwarded to the confirmation step.
6. Refresh the page to have the app updated to display the confirmation page.

Expected behavior

The feedback page triggers a reload/refresh or something that makes the app load in the instance in its correct step.

Additional info

The system works if the step following the feedback step is an EndEvent. It's not important what the EndEvent is called.
