Description
When rendering a PDF exported from InDesign, the background image does not appear in Safari. Testing in Chrome shows the background renders correctly.
After verifying our implementation and testing different configurations, the issue also occurs in the PDF.js live demo on Safari. This strongly suggests the problem lies within PDF.js itself.
