Created attachment 373617 [details] iOS WebKit crash report There is a WKWebView running on iOS 12. Inside that WKWebView there is a piece of JavaScript code that uses window.webkit.messageHandlers to post message to the native side. The code works fine when it is being invoked from any website element like button, etc. When trying to invoke the same code using WebInspector's console - I can observe that there is webViewWebContentProcessDidTerminate(_ webView: WKWebView) called inside the application that owns the webView and attached crash report is generated.

Can you attach the code in question? Would it be possible for you to create a small reproduction so we can test it?
