Description Karl Dubost 2024-02-21 15:28:18 PST

Steps to reproduce:
1. On iPhone with Safari
2. Go to https://www.booking.com/hotel/us/milpitas-40-ranch-drive.html

Expected: 
See the images

Actual:
Images are not visible. 


Why This is happening:
Because JPEG 2000 has been removed from WebKit. (Bug 178758)
Booking.com for Safari on iOS sends JPEG2000 versions of images in the raw HTTP responses for each HTML requests.
This is currently not detectable on released versions of Safari of iOS.


Outreach effort has been started.
See https://github.com/webcompat/web-bugs/issues/133697


FIX:
Proposal for the Quirk to fix it.

* On iOS *only*
* On booking.com *only*
* Sends the following `Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8` for HTML HTTP requests.
* No need to modify the Accept HTTP request headers for images requests.
