Steps to reproduce:

1. Create a form with 5 fields (one select field and 4 text fields) and all are required to fill.
2. Go to Rule builder.
3. Create rules like below
   1. In case the user selects the first option from Select field will 'show' second field (text field) field.
   2. In case the user selects the second option from the Select field will 'show' the third field.
4. Save rules
5. Remaining two fields will have no rules applied.
6. Save the form.
7. Create one page and add the above-created form.
8. Select the first option or second option and fill in the text fields and try to "submit".
   Result: Nothing happens and seemingly no errors anywhere.
   Expected: Form should be submitted
