Bug description
I get a blank window on Safari 18.6 – except for controls along the top – when clicking on a PDF in the Files app whenever its the first time in a new window. If I then close that viewer and click on the PDF again, it will load fine.
The console log is showing the error:
[Error] TypeError: Right side of assignment cannot be destructured
Module Code (pdfjs.js:59)
which points to this initialization code:

} = globalThis.pdfjsLib;so I'm guessing that this is some async issue to do with loading.
Steps to reproduce
- Open a "Private" window (easiest way to get a fresh session)
- Go into Files app
- Click on any PDF
Expected behavior
The PDF loads properly first time.
