Controls with role="presentation" do not need labels.

Adding role="presentation" is an explicit declaration by the developer to hide the elements native semantics from the accessibility API, and thus should be ignored.

I can take it or leave it. It saves a little typing/reading but it'd be a one line method so the benefit is really pretty minimal. I wouldn't push back on it if you implemented it, though :)
