Bug 167898 – [iOS] -[WKWebView becomeFirstResponder] and -[WKWebView resignFirstResponder] don’t get called when non-programmatic first responder changes happen

• Component: WebKit2
• Status: RESOLVED FIXED

Because the child WKContentView can and does become first responder, WKWebView’s -becomeFirstResponder never gets called by UIKit. Similarly, because the WKWebView is never the first responder, its -resignFirstResponder is never called.

This means that overrides of these methods in a WKWebView subclass normally don’t get called.

usesStandardContentView?

ScopedChange? or whatever we called it?
