Edit Schedule on expired session doesn't log out user

## Describe the bug
If a user's session is expired and he presses the Edit Schedule button, the editor pop-up will open. But this edit pop-up will be "broken" in a sense that user is not able to select, increment or type anything, which then seems like a broken scheduler instead of a session expired.

## To Reproduce
Steps to reproduce the behavior OR commands run:
1. Login in
2. Pick Dataset
3. Wait for session expired
4. Edit schedule

## Expected behaviour
On pressing edit schedule I am shown the login screen

No files, tests, or entry points are identified in the issue. Reproduce the flow by logging in, selecting a dataset, waiting for the session to expire, and choosing Edit schedule; done means the login screen appears instead of a non-interactive editor popup.
