fix(replay): Ignore layout changes on non-latest root in WindowRecorder

rootViews is a stack of windows (dialogs, popups, IME). The recorder
binds to the topmost root, so a background activity resizing underneath
a dialog must not reconfigure the recorder — we'd otherwise allocate a
bitmap sized to the activity while still recording the dialog. The
latest root's correct dimensions are already picked up via
determineWindowSize in the onRootViewsChanged remove path when the
overlaying window dismisses.
