REGRESSION(307380@main): Possible null pointer dereference in
WebPageProxy::takeSnapshot() when RemoteSnapshotting is enabled
https://bugs.webkit.org/show_bug.cgi?id=316814
rdar://172363560
Reviewed by Abrar Rahman Protyasha.
WKWebView -takeSnapshotWithConfiguration: can be invoked on a WKWebView whose
underlying WebPageProxy does not (yet, or any longer) have a main frame attached
— e.g. shortly after process exit/relaunch, during teardown, or before the first
provisional load installs m_mainFrame.
So having uninitialized m_mainFrame is an expected case that WebPageProxy has
to deal with safely.
