As per @jonathan1055 comment in #75, 🐛 FileItem::generateSampleValue() should generate files with the actual allowed extensions Needs work I think we should go back to @dww's patch in comment #36 🐛 FileItem::generateSampleValue() should generate files with the actual allowed extensions Needs work .

Created an MR for that.
