1728345 - [PDF Viewer] Image in PDF not cropped when it should be (i.e. appears as cropped in other viewers)

Status: RESOLVED FIXED

(Firefox :: PDF Viewer, defect)

Description

[joshuatiger1]

Attachment: datasheet.pdf from https://chroniclesystems.co.uk/content/general/hosting-page/datasheet.pdf

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:91.0) Gecko/20100101 Firefox/91.0

Steps to reproduce:

1. Download PDF from https://chroniclesystems.co.uk/content/general/hosting-page/datasheet.pdf (file is also attached to this report).
2. View in FireFox (Windows 10 Home) - observe that large splash image covers entire page (obscruing some content).
3. View in Google Chrome or Adobe Acrobat Pro - observe that image is only crapped behind "C" logo, presumably as intended.

I presume a similar issue could also occour on other PDF documents, but I don't have any other examples.

Actual results:

Image covers entire page, obscruing some content.

Expected results:

The image should have been cropped to a specific area on the page.

MacOs 10.15 and Ubuntu 20 looks ok. On windows 10 it looks incorrectly
