If this is deleted with the constrained window open won't the
ConstrainedWindowViews still have a reference to 'this' by way  of the
WidgetDelegate?

yea, but the plan is not to let that happen (i.e. it would be an error to get
here if the constrained window hadn't already started closing). I've added code
to catch this problem.

+void AutofillDialogViews::Show() {
+  InitChildViews();
+
+  // Ownership of |contents_| is handed off by this call. The ConstrainedWindow
+  // will take care of deleting itself after calling DeleteDelegate().
+  new ConstrainedWindowViews(
+      controller_->web_contents(), this,
+      true, ConstrainedWindowViews::DEFAULT_INSETS);
+}
+
+string16 AutofillDialogViews::GetWindowTitle() const {
+  return controller_->DialogTitle();
+}
+
+void AutofillDialogViews::DeleteDelegate() {
+  // |this| belongs to |controller_|.
+  controller_->ViewClosed(AutofillDialogController::AUTOFILL_ACTION_ABORT);
+}
+
+views::Widget* AutofillDialogViews::GetWidget() {
+  return contents_->GetWidget();

+
+const views::Widget* AutofillDialogViews::GetWidget() const {
+  return contents_->GetWidget();

+
+views::View* AutofillDialogViews::GetContentsView() {
