HTMLFormElement probably shouldn't have [OverrideBuiltins] #1562
Description
None of the HTMLCollections have [OverrideBuiltins], which means that HTMLFormControlsCollection doesn't. Thus the following snippet holds:
var form = document.createElement('form');
var input = document.createElement('input');
input.name = 'length';
form.appendChild(input);
console.log(form.length === input) // prints true
console.log(form.elements.length === 1) // also prints trueIf there's value in not letting form control names override IDL attributes for HTMLFormControlsCollection, it seems like the same logic should apply to HTMLFormElement itself. Unless, of course, this is some legacy requirement.
