Created attachment 268980 [details] Simple app that repros the bug. When certain pages are loaded when the WKWebView is not part of the app's view hierarchy and with a frame of CGRect, the certain click handlers in them are not fired. Steps to Reproduce: 1) Run the attached code. 2) Wait for page to load and scroll down until the "read more" button is shown 3) Click on the "read more" button This problem is more pronounced on a site such as http://www.cnn.com/2016/01/11/americas/mexico-sean-penn-el-chapo-capture/index.html. See example code for an example app. Expected Results: Clicking on the read more leads to the rest of the content being revealed/loaded. Actual Results: Clicking has no effect Version: iOS9.2 Extra notes: What's interesting is that the problem goes away if an initial frame is set on the WKWebView. Configuration: iPhone 6S and Simulator

Update: setting the initial frame does not always fix it and instead fixes it unreliably.

Did you mean "with a frame of CGRectZero"?

Yes; sorry, looks like a typo on my part. s/CGRect/CGRectZero s/the/then To double confirm, the following preconditions need to be satisfied 1) frame = CGRectZero 2) webView.window = nil The example app should illustrate this.
