We have an application mostly consisting of a WKWebView that displays a web app. When the web app uses the JavaScript function scrollIntoVew a couple of times, parts of the UI freezes and becomes unresponsive. This is not a problem on iOS 10.
Does this ring a bell with anyone?
I have boiled the application down to a simple testcase, and submitted a bug report (#33874196, rdar://33874196) to Apple, but have not yet received any response.
