Description Boris Zbarsky 2014-08-05 01:31:44 UTC 
For example, this case:

  <form>
    <input name="action">
  </form>

should return the input when you do form.action but should set the "action" HTML attribute when you do form.action = "something".  This requires defining a [[Set]] hook that does a normal [[GetOwnProperty]] for non-indices, ignoring the named props.

There are multiple testcase in https://bugzilla.mozilla.org/show_bug.cgi?id=1043690 for various aspects of this behavior which show that UAs are not very interoperable on it.  What the behavior should be is not clear and I've had no luck getting any of the other browser vendors to comment on this issue so far.
