Is it okay to save |web_contents| off like this for the life of the tab? Do I
ever need to check if it's gone away or become invalid?

+      state_(INACTIVE_STATE) {
+  DCHECK(web_contents);

This seems a little awkward. This API feels more like this method should be
called CreateBubble() and ReshowBubble() should be named ShowBubble(). Assuming
you follow Evan's suggestion to have the controller create and own the view,
this is what you'd be doing anyhow (I think).

[bondd, 2015/10/15 22:27:07]

Done. I flip-flopped a couple of times between these exact two combos,
ShowBubble+ReshowBubble vs CreateBubble+ShowBubble. Thanks for casting the
deciding vote!

This function is based on the one in ManagePasswordsUIController.

[Justin Donnelly, 2015/10/13 16:25:53]

Is there a motivation for not resetting the timer at the end like
ManagePasswordsUIController does? 

[bondd, 2015/10/15 22:27:07]

Yes, I considered resetting it at the end like ManagePasswordsUIController does,
but I can't figure out what problem that is solving. Perhaps it is solving
something that is an issue for passwords but not for SaveCardBubble, or maybe I
am missing something. AFAICT it doesn't add anything good to SaveCardBubble, and
SaveCardBubble works fine without it, so I left it out.
