Prior to microsoft/TypeScript#25944, HTMLFormElement had an index signature [name: string]: any;. That's probably too broad, but it looks like it should have something -- according to [mdn](Named inputs are added to their owner form instance as properties) "Named inputs are added to their owner form instance as properties".
This affects braintree-web on DefinitelyTyped.
