PDF form not being handled properly

SUMMARY
There is a PDF form to Tax Office in The Netherlands which is not being handled properly. The file is available at https://www.belastingdienst.nl/wps/wcm/connect/bldcontentnl/themaoverstijgend/programmas_en_formulieren/aangifte-melding-opgaaf-bpm - the first link, titled Aangifte/melding/opgaaf bpm (pdf - 427kB). I have attached the file for reference as well.


STEPS TO REPRODUCE
1. Open attached file in okular
2. Goto second fillable field "Documentkenmerk (Laatste 7 posities van het VIN)" 
3. Try to enter anything into this field.

OBSERVED RESULT
Nothing happens

EXPECTED RESULT
One should be able to enter data into this field.

It might be possible this field is being auto filled after filling the first one, for VIN, however this scenario does not work as well. In that case it could be related to #344776.

As far as i understand there's javascript in the file to copy the relevant bits from the first line to the second line, we're just failing to deal with that correctly
Comment 2 Artur R. Czechowski 2019-01-26 19:37:25 UTC 
Probably you are right. I've finally found a software where it works (guess, what is it...) and, indeed, part of the first field is being copied to second field.
