In this PR, I'm fixing two things on the ViewPicker in Create mode:
- if the Dropdown has no max height, it should not be scrollable (which
is causing issue with inner dropdowns being cut by overflow: hidden
- if the user has changed the icon, the type or the name of the view,
consider the create form as isDirty and prevent its value to be
overriden by re-renders (cache updates for example)
