Done.

Typically, if you don't own an object (like this object does not own dialog_)
the typical idiom is to add a comment like:

// Weak ptr to parent dialog.

This means that we don't own the dialog and don't manage its lifecycle (so we
probably shouldn't document when it frees itself here).

Done.
