A web page using a third party AJAX control has a different behaviour between iOS devices when displayed with WkWebView. Correct on iPhone SE (2nd gen) and iPhone 7 Plus physical devices. Incorrect on iPhone 12 Pro Max simulator. Build and run the sample at this link: https://github.com/omatrot/wkwebview It should be correct whatever the target device. It is incorrect on the iPhone 12 Pro Max simulator. The html page included in the demo project could be displayed directly in Safari where it is working fine.

I do not own an iPhone 12 Pro Max physical device. I can't confirm this is a simulator related issue only.
