Opening PDF from public link broken

[kulmann]

Steps to reproduce

1. Share a PDF file via public link
2. Open public link
3. Either click Open in browser in the actions accordion of the right sidebar or click on the filename within the file list (Open in browser is the default action for pdf files)

Expected behaviour

The pdf file should be opened in a new browser tab

Actual behaviour

The browser shows a blob:// url but shows an error message like Failed to load PDF document. (see screenshot). Blob download in the network tab looks ok (has a reasonable content length and shows 200 OK).
