Restore from cache retrieval failed after closed page by accident

[demshy]

Describe the bug
This issue was caught here: #6964
When retrieving values from backup, the page gets reloaded after a while, reverting to the values previously saved.

To Reproduce

1. Open an existing entry
2. Change some values
3. Reload page
4. Choose to retrieve from backup when prompted
5. Observe that the page reloads after a while

Expected behavior
The form should keep the values that were retrieved from backup and should not refresh.
