@gabor How can I test this?

[tinuademargaret]

I think we could have done something like this here
custom_form_field_names = list(custom_form.fields.keys())
what do you think?

[gabor-boros]

I agree, this could be simplified, though it is already merged on edX master and possibly I wouldn't make an unnecessary code drift.

[tinuademargaret]

Sure! sounds reasonable.
