[Forms] Can't edit the attached form nor any warning about it #4358

SumatraPDF version

Describe the bug Two problems:

  1. Can't edit the form of the attached pdf. It is open as a "static" pdf file.
  2. SumatraPDF doesn't even give a warning that the pdf contains a form that is potentially unsupported. This could work as a hint to the user to open it in another editor. I have seen this warning in other pdfs but for some reason it isn't triggered on the attached pdf.

Opening it in the internal pdf editor of Firefox works. But I discovered that it was a form too late and ended up completing it by hand after printing it. Lol.

Hmm Acrobat does not say a form is a form in general it simply shows the blue fields of an Acroform for filling. OR alternatly intentionally seeks out Lines for writing on and and also OCRs dumb boxes to edit with a cross. (Reader is a mini Pro) image

SumatraPDF only "Warns" like others when an Adobe proprietary PDF is not a standard PDF by saying the file is an XFA (Form) thus the view cannot be trusted.

MuPDF does have the ability to fill standard Acroforms but that is not currently enabled in SumatraPDF, as its a greater resource ability/custom programming than simply adding underlines or highlights. So is on the "Agenda" but perhaps much later than sooner. Clearly you can for simpler forms use a browser but for XFA you MUST use Adobe.
