Description

around 1 August 2026, drag-and-drop of a PDF file (from same source I've used before) stopped working.

PNG screenshots continue to process ok.

Did the PDF.js change API? Would it work if the prior version were specified?

Research direction

Start by reproducing the drag-and-drop failure with a PDF and compare it with the still-working PNG path, then inspect the PDF.js integration and its recent API assumptions. Done means PDF files from the reported source process successfully again without regressing PNG handling.
