Conditional rendering not updating when field is updated after record is saved

Hello -

After a record is saved on a page (no redirect, stay on page), changes that should trigger conditional rendering to show/hide elements are not resulting in expected behavior.

Steps to Reproduce:

1. Create Contact new page
2. Add a tabset with 2 tabs
3. Put default field editor in to tab #1
4. Set tab #2 to conditionally render when first name is not blank
5. Add template field to tab #2 with “hello {{{FirstName}}}”
6. Remove values for “After Save Redirect URL” and “After Cancel Redirect URL” from “Save” button
7. Preview page
8. input text in to first name field

Actual Result = Expected Result
Tab #2 appears

9. remove text from first name field

Actual Result = Expected Result
Tab #2 disappears

10. Input text in to Last Name
11. Save Record
12. input text in to first name field

Actual Result
Tab #2 does not appear

Expected Result
Tab #2 appears
