[Bug/Help]: I have a pdf file not shown correctly on iOS 15.7 (this happens with latest/v4/v3/v2)

[zhaojjiang]

PDF file: test.pdf

Steps to reproduce:

• gulpfile.mjs ENV_TARGETS set Safari >= 15 --> default build targets not work on safari 15, so i changed it to check.
• npx gulp generic-legacy
• serve build/generic-legacy
• the problem is: part of image not shown.

as you see, the first render result has less content.

I tried to downgrade pdf.js to v3/v2, it not work.
