[experiment] paste: show little puff when pasting to denote something happened (#2787)

@steveruizok go ahead and take a look at the animation css and tweak as
you like.
@SomeHats and @steveruizok this is an experiment in that this is prbly
the wrong way to approach it? But I'd be curious to learn if there was a
more proper route here
