--- Comment #6 from Alex Ruar <bugzilla at rutar.org> ---
This is perhaps related: it seems that the CSP violation sometimes causes PDF height to be severely truncated in the viewer.

Here is an example URL: https://rutar.org/papers/assouad_interpolation.pdf

Inspecting the source shows the following error:

> Refused to apply a stylesheet because its hash, its nonce, or 'unsafe-inline' does not appear in the style-src directive of the Content Security Policy.

The same PDF is viewable in Safari if first downloaded, with no issue. There do not seem to be issues viewing the PDF with non-webkit browsers either. There do not seem to be issues on iOS or iPadOS.

Versions:
Safari 16.5.2 (18615.2.9.11.10)
Ventura 13.4.1 (c) (22F770820d)
