attributeBinding with properties not available in element prototype do not get set.

[rwjblue]

We do a attrName in element check to see if a property exists for a given attribute, and if it does we set it as a prop, but if not we use setAttribute. In the case of novalidate on <form> elements, it is not a property, so we fallback to setAttribute (which leads to it not being added to the DOM).

@mixonic - Can you confirm my summary (I may have the prop/attr thing backwards)?

[wagenet]

By the way, it looks like noValidate (camelcased) is a property. So document.createElement('form').noValidate = true does what is expected. If I camel-case the property then it looks like it works: http://emberjs.jsbin.com/yadawejase/1/edit.

@wagenet there is normalization code that should have caught that. I believe the issue would be in setProperty. There are tests around it elsewhere (using maxLength as an example), but perhaps you have unearth a bug in the caching code or something.

[wagenet]

It turns out this is not a new regression. It last worked in 1.7 where it rendered <form novalidate='novalidate'>.

I was seeing the same issue in #10183

Is there anything I can do to help?

[rwjblue]

There is no normalization for attributeBindings (in 1.9, 1.10, or canary at this point). The good news is that #10186 should fix this (since it would then go through the normalization that happens in AttrNodes), but sadly I do not think that it will make it to beta (it is a pretty big change to make so late in the beta cycle).

@kiwiupover - Off the top of my head I do not believe #10183 is related to this, but I'll try to dig around to confirm/deny.

@rwjblue thanks. Thanks heaps for all you are doing.

Looks like this is working now: http://emberjs.jsbin.com/xuyubejida/edit?html,js,output
Can you confirm @rwjblue ?

this behavior is now exactly what we want (and exactly the opposite of what it was.)
