I'm confused - this seems to re-attach an existing bubble to a new delegate?

Doesn't that leave contents from the previous bubble around? I'd feel better if
we closed and re-opened a bubble when a delegate changes.

It's just here as an early return.  The delegate itself should control the
closing and re-showing of the bubbles.

+    return;
+  if (delegate_ && delegate)
+    delegate_->SetView(NULL);
+  delegate_ = delegate;
+}
+
+void PermissionBubbleCocoa::OnBubbleClosing() {
+  bubbleController_ = nil;

delegate_->SetView(NULL) here? I'm not clear on the lifetimes of the involved
objects. Maybe document in header?

[leng, 2014/03/03 19:01:04]

No, because the delegate might still have 'control' of the view, and re-open it
with a different request.
