If that expression doesn't return null, it will have a setAttribute method.
However, `document.getElementsByName('foo')` is actually returning elements
that have an attribute with `name="foo"`; are you intending to use
`getElementsByTagName`? If you are actually using `getElementsByName` you
should probably just stop (our DOM engineer says it's "an abomination",
lol).

attributes there
Today, ShadowDOMPolyfill does not provide a patched version of
`getElementsByName`; if you really want to use it you have to `wrap` the
return value:
var element = wrap(document.getElementsByName('somename')[0]);
>> FWIW if you edit the attribute from the DOM Inspector it also doesn't
update Polymer!
On platforms using ShadowDOMPolyfill, you have to be careful what
techniques you use use to poke elements in the dev tools. If you stick to
'querySelector' you generally will be ok. If you describe exactly what you
are doing in the console (and in what browser) I can give you more
information.
