Bug 284510 – Remove Quirk needsIPadMiniUserAgent for cctv.com

• Status: NEW
• Component: WebKit Misc.

[Karl Dubost]

Currently on regular iPad, cctv.com is receiving iPad Mini User Agent instead of the traditional desktop user agent.

Initially this Quirk was added through Bug 198484 on 2019-06-04
https://github.com/WebKit/WebKit/commit/4bb8f0f34179bd8ed4dcafeda205f65b5b8d6c87#diff-d2eb30e968da05615b61df7746f0d13b708da1629b083d455e1f98de80367bebR1293-R1295
then moved later on to 
https://github.com/WebKit/WebKit/blob/ba1fbaadee0af044adad5a31c2eca663007c44b2/Source/WebCore/page/Quirks.cpp#L1677

The reason for adding it is at the time this site is that receiving the desktop UA, some sites were sending the Flash Player to the users which was not supported on iOS devices. 
The Flah player end of life was programmed for 2020. 

This needs to be tested with Quirks disabled. If the site is working without the iPad Mini UA, then we can remove this quirk.

With the iPad normal UA string (aka desktop), we can see a perfectly normal website.

* both portrait and landscape fit exactly the window width

Most of the homepage links open to subsites such as 
https://tv.cctv.com/2024/12/11/VIDE74ZoCjjwl5XcUn2aAjb3241211.shtml

The video is not starting. They are using this player.

The same url on a desktop computer
https://tv.cctv.com/2024/12/11/VIDE74ZoCjjwl5XcUn2aAjb3241211.shtml
loads the video after advertisement has played.


Another test the video is working with iPad Mini UA

```
> window.location.href
< "https://tv.cctv.com/2024/12/12/VIDEKtwzgIt3xO6Dw3uiIb8a241212.shtml?spm=C28340.PImrkkn9UZ9h.EHuWA8qIunFk.1"
> navigator.userAgent
< "Mozilla/5.0 (iPad; CPU OS 18_2 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/18.2 Mobile/15E148 Safari/604.1"
```

But as soon as I switch to desktop UA for iPad, it doesn't work anymore.
