Experimental Event InputEvent has readonly data attribute

[xuorig]

I started getting Uncaught TypeError: Cannot assign to read only property 'data' of object '#<InputEvent>' with a flag on chrome.

This line being the culprit https://github.com/madrobby/zepto/blob/master/src/event.js#L68

The new InputEvent spec has an actual data attribute, clashing with Zepto's.

Seems like the real fix would be to deprecate data on the event and use something else, or return a custom event instead of modifying the DOM Event itself.

It will because a big problem soon when this is not experimental I believe.

Closing this as I can't reproduce.

"use strict" will cause this bug

and you should update chrome to 60+ or iOS 10.3+ ... I reproduced it too @madrobby

This issue is happening if you add an event to the input event

Same issue today, with Chrome 68. Nothing in dev environment, but the error is fired on production (webpack 4).
