opening zip archive with pdf as a first file fails

[durdin]

I've first faced it with Intel NUC 10 BIOS zip file (either UEFI or Recorvery version) from ​https://www.intel.com/content/www/us/en/download/19485/bios-update-fncml357.html, but as tested it happens with any zip file which has first entry as a PDF.

When you try to open it in MC (by hitting Enter on it) and when in X-session it opens the system archiver, hitting "enter" on the file in base terminal without X-session attempts to parse the zip via some console pdf viewer but obviously fails with:

Syntax Warning: May not be a PDF file (continuing anyway)
Syntax Error: Couldn't find trailer dictionary
Syntax Error: Couldn't find trailer dictionary
Syntax Error: Couldn't read xref table

Trying to view the zip via the "F3" results in an error: Syntax Warning: May not be a PDF file (continuing anyway), but nothing happens.
