Please update the Harmony *popover* dialog template to include X. 

UI Review (2017 Feb 28): go/crhcxur

Popover dialogs (previously anchored dialogs/infobubbles): 

Spec: 
- Close X on all desktop platforms
- No Cancel button if it’s redundant (Note: removing the existing cancel buttons should be scoped for post V1)

Rationale:
- Optional offering: Popover contents in Chrome are typically optional offerings initiated by Chrome features. The user should be able to dismiss them quickly when not interested, without needing to read the content. 
- Visible cue: Clicking-out is a nice hidden dismissal gesture to continue to keep, however, that should not be the default way since it’s not immediately discoverable and also, notably, clicking-out often triggers to open an ad. A visual element is a more reliable way to dismiss a popover.

Note: Harmony *modal* dialogs have *no* X, and do have a labeled button (tracked in a separate bug).

Thanks!
