exportAsFDF: values are exported from fields not in the array
Steps to reproduce the issue: Create an exportAsFDF script in a privileged context in a folder level script. Specify an array of some but not every child field of a non-terminal field name using the aFields parameter with exportAsFDF. Next, employ ALL child fields of that multi-field set a pdf, not just the fields in the array, and enter values in every field in the family. Call the script from the pdf to export and save the fdf file. Reset the fields in the pdf to a blank state. Import the fdf file to that pdf.
Environment: Acrobat Pro DC; Mac OS High Sierra
Expected result: only the field names and values of the specific fields in the aFields array should be exported.
Observed result: child field names and their values from the same non-terminal parent are exported with the array even though they are NOT included in the array.
