ACTION-5 and ISSUE-3: Popup/Dismiss Request events already covered by DefaultAction (aka 'click') and DismissRequest (previously EscapeRequest)

Clearing through some of these items:

Popup (in the case of popup buttons, dialog) is already covered by DefaultAction, aka 'click' events. DismissRequest is already in the spec (previously called EscapeRequest), but applies to a much broader scope than just dismissing popups.

I am intrigued by the prose used for popup though ("context menu") which implies triggering of a secondary action, regardless of whether than secondary action triggers a primary or secondary "popup" so I've raised ISSUE-3 separately.

Unless I hear objections, I'm not adding the following changes.


> Popup (see related Dismiss event below)
> User triggers presentation of a context menu -- a set of operations relative to the current context. In future, this may be something other than a menu. (Focus or point-of-regard is relevant here, since it defines the context of the popup. Also, the popup acquires focus or point-of-regard when presented).
> 
> Bubbles: Yes
> Cancelable: No
> Context Info:
> The context that the popup is associated with.

> Dismiss (see related Popup event above)
> User dismisses presentation of a previously displayed popup. (Focus or point-of-regard returns to the context associated with the popup after the popup is dismissed).
> 
> Bubbles: Yes
> Cancelable: No
> Context Info:
> The context that the popup is associated with.
