On iPhone, PDF viewer jumps around while pinch-zooming in and out

[ush]

Steps to reproduce

1. On iPhone (16 Pro, if it matters), create a new vault
2. Add the PDF file that I shared with WhiteNoise via DM and open it
3. Use the pinch gesture to zoom in and out.

Did you follow the troubleshooting guide? [Y/N]

Y

Expected result

The PDF viewer should zoom in and out within the same page.

Actual result

While zooming in and out, the PDF viewer jumps across different pages. Moreover, the app sometimes reloads itself.

(Please look at the page number; this is a cropped version, but I also sent the uncropped original video via DM)

Additional information

• This bug does not happen in every PDF file.
  The PDF I shared with WhiteNoise is not the only one that suffers from the bug, however I have not found a PDF file that I can share publically where this happens. I will update when I do so.
• The page jumps tends to be more noticeable when you zoom in or out relatively fast.

Meet the same problem. Wonder why this bug has not been fixed yet. It’s awful .
This problem seems to happen every time I use mobile devices to inspect PDF files.
