rdar://177788035
Reviewed by Abrar Rahman Protyasha and Pascoe.
A client who overrides - [WKWebView setFrame:] can enter various frame
adjustment codepaths during WKWebView initialization, before WebPageProxy
has been created, resulting in a crash. Add a null check to avoid this.
Test: WKWebView.SubclassedSetFrameDuringInitDoesNotCrash
* Source/WebKit/UIProcess/API/ios/WKWebViewIOS.mm:
(-[WKWebView _dispatchSetViewLayoutSize:]):
(-[WKWebView _frameOrBoundsWillChange]):
(-[WKWebView _frameOrBoundsMayHaveChanged]):
Bail if _page is not initialized yet.
* Tools/TestWebKitAPI/Tests/WebKit/WKWebView/WKWebViewSubclassedSetFrame.mm:
Add a test.
