Unable to export to PDF with dark theme

• [x] Searched existing issues to avoid creating duplicates.

  • There are multiple closed issues about this... But I don't think it has been fixed.

• [x] Confirmed that it can be reproduced in built-in themes without customized CSS.

  • I am testing w/ Night theme, and the issue persists.
  • 

  If it only exists in 3rd party themes or css, you can still report it, but please attach the theme target or the css file. We may not "fix" it, if it is caused by 3rd party themes or css styles that we cannot support.

  • This also happens to 3rd party themes. And weirdly enough, I was able to export pdf w/ the exact same 3rd party theme back in the day when this app is still in beta...
