[Tabs] Aria-Hidden used in JS is tripping accessibility checkers

[trlrunner]

When using the code to incorporate tabs on a webpage, aria-hidden="true" is causing accessibility flags. It appears to be in the JS as it's not hard-coded into the HTML or CSS. Since the ah-true is pretty much never needed, is it necessary here, or is there a way around its usage? Otherwise, the design is great and excellent to use.
