Issues with autoCorrect attribute set as property

Hey. As far as I can see, the autoCorrect attribute are set as an HTML property.
https://github.com/facebook/react/blob/master/src/renderers/dom/shared/HTMLDOMPropertyConfig.js#L194

This can give issues with Input elements. Check this :

• Chrome 46.0.2464.0: autocorrect in document.createElement('input') === false
• Safari 8.0.7: autocorrect in document.createElement('input') === false
• Mobile Safari (iOS 8.4 simulator): autocorrect in document.createElement('input') === true

There are identical issues with some other browsers as well.

This is not tested on iOS 9.x

autocorrect is only supported in mobile Safari AFAIK, which explains your results. FYI your test passes in iOS 9(.1 in a simulator, didn't test on real device but I trust the simulator).

On desktop, the attribute is ignored and actually, it looks like spellcheck does pretty much the same thing in Safari.

Now that said, the property is a boolean and the attribute supports 'on' and 'off' as values (corresponding to true/false for the property). With our markup generation code, we don't currently support booleans properties corresponding to specific values in the attributes so the best course of action here is probably to do what you suggest and just make this MUST_USE_ATTRIBUTE

@zpao I've searched far and wide for an official answer on this and it looks like i might be close, can you confirm for me: Should i use 'off' or false/'false' for autoCorrect and autoCapitalize?

@JemarJones If it is listed as a boolean property in HTMLDOMPropertyConfig then it should be either boolean true or false, otherwise it's passed through as a string as-is and whatever value the HTML attribute expects should be the one to pass (different for different attributes).
