When a field editor section is marked to not show a section header, if the “collapsible?” property was “yes - initially collapsed” prior to turning off the header, the field editor section does not render at all.

Steps to Reproduce:

1. Create new detail page for account
2. Set the “Basics” section Collapsible property to “Yes - initially collapsed”
3. Set the Show Section Header to false
4. Save page
5. Preview page

Expected Behavior
Basics should show without a section header

Actual Behavior
Basics doesn’t show at all
