[NTG-context] Disable form fields, keep layout

If I disable interactive elements with \setupinteraction[state=stop], my form fields (widgets) disappear. This is of course intended, but I’d like to keep their space, because otherwise my form layout breaks completely. Is there any option to disable form field generation, but keep their size (i.e. their framed structure)? I need the same form for print and for online use, and it’s inconvenient to kick the fields out using Acrobat Pro...
