Enhancement: Hide field with when clause when parent field its when clause is not met

[estruyf]

So it is the following behavior that we need to get fixed:

Steps:

• You publish the page
• The state field its condition is met and shows up
• Change the state field its value to superseded
• The superseded_by field shows up
• Set the page as draft -> the state field disappears, but the superseded_by field is still shown

Outcome

The wanted outcome should be that the state and superseded_by should not be shown in the UI.
