[clipboard-api] Do paste events and company bubble?

[Boris Zbarsky]

The clipboard API draft [1] doesn't seem to say whether paste events, or 
any other events fired by "fires a clipboard event" bubble.  Or whether 
they're cancelable, for that matter.  Presumably it should say something 
on the matter.
