When the installation reaches the passphrase stage,
- the checkbox is checked and the passphrase inputboxes are visible (expected behavior)
- I uncheck the checkbox and the passphrase inputboxes go away but the checkbox remains checked
- I uncheck the checkbox again and the passphrase inputboxes don't show up but the checkbox is now unchecked
The sequence of events described above is reproducible in calamares 3.2.7-0pureos3 as well as in calamares 3.2.11-0pureos1
