Synthetic events proxy doesn't work for normal synthetic events

[zpao]

This blames to #5939, cc @kentcdodds

Not sure yet if this is affecting all load events or just ones that are attached directly to nodes (for eg image). But the problem is that when we intercept set operations for SyntheticEvents (but not "subclasses" like SyntheticMouseEvent), we don't have target.constructor @

react/src/renderers/dom/client/syntheticEvents/SyntheticEvent.js

Line 199 in 36798f7

!target.constructor.Interface.hasOwnProperty(prop) &&

Simplest repro: http://jsfiddle.net/ge8b0np9/ (will still fail w/o the load listener)

Isn’t this #5947 by @koba04?
@kentcdodds’s #5939 was similar but it didn’t use constructor or proxies.

oops, yea. Sorry for getting the blame wrong!

Was just about to ask that :-)
