[6.x] Dependent field conditions

[jasonvarga]

Bug description

When a field has a condition based on another conditional field and you update the first field, the third field doesn't take effect.

[field 1, toggle]
[field 2, text, condition: show when field 1 is true]
[field 3, text, condition: show when field 2 is not empty]

enable field 1, you see field 2. field 3 is hidden.
type into field 2, field 3 appears.
disable field 1, field 2 disappears, field 3 remains but should also disappear.

Additional details

This was initially solved in #11910, but regressed in #12362 (semi-intentionally). I felt that issue was more important to get out there than this one which is more of an edge case.
