Description

Hi, noticed the following issue running MacOS version 10.12.5 (16F73) and MacDown version 0.7.1 (870).

Steps to recreate:

  • Open or create any document
  • Hide the Preview Pane (Command-Shift-H)
  • Type anything
  • Print (Command-P)
  • Notice that the new content does not show up in print preview or if you generate a PDF
  • This also happens if you chose to export PDF (Alt-Command-E) or HTML (Alt-Command-P)

Research direction
Investigate how the preview pane's hidden state affects document rendering for print and export. Look at the print/export code in MacDown (e.g., MKPrintView or Document.m). The issue (2017, 6 comments) may contain clues. Focus on how the preview visibility flag interacts with content generation for printing.
