crbug/788271 is a mystery, crashing in objc_msgSend without triggering
any zombie warnings.

crbug/808318 points to a leaked WidgetObserver affecting all platforms,
but has no indication of what the observer is, or what window it observes.

Record class names and the window title in crash keys. The window title
is usually set by the framework, even if it is not displayed anywhere.
