q: Should this use GetInternalWidget (and bail if null)? Something else?

[sky, 2016/07/26 13:25:20]

It's possible to make the non-internal widget case work, but we can figure that
out later if necessary. How about extending the comment in
AddLimitedPreTargetHandler to indicate only for windows associated with a widget
and a DCHECK(GetInternalWidget()) ?

Done.
