$(document).on() not working with name="disabled"

[stevene]

If a form includes an element with a name attribute of 'disabled', the .on function does not prevent the form from being submitted (when used with a descendant selector).

This form is not prevented from submitting:

<form action="google.com">
    <input type="text" name="disabled" value="Some text" />
    <input type="submit" />
</form>

$(document).on('submit', 'form', false);

If the name of the text input was changed to anything other than 'disabled' the form is prevented from submitting.

Strangely, if I change the method to the following, the original form would not submit (even with the name="disabled" attribute)

$('form').on('submit', false);

Example: Two identical forms, one with name="disabled"  http://jsfiddle.net/y3HVA/

Note: I am not trying to disable this field, I simply wanted to use the name 'disabled' as the attribute.

Confirmed. To fix #6911, jquery.event.dispatch delegate handler processing requires !event.target.disabled. In this case, both event.target and event.target.disabled are elements... the former a form and the latter a contained input.

I recommend we instead require event.target.disabled !== true.
