I would guess that it does not interact with accessibility now.
These components are just bunch of styles to make it look like a 'native' widget, though it's not a real native widget of OS.
Though, it leaves me with a question, how can you set up OS X accessibility features, in your web app/UI, that it could be used by OS X? I would guess you can't, and it's all left to the browser.
WebKit supports ARIA attributes. If you aren't using them in your web code already, VoiceOver can probably navigate your page just fine, but it's subpar compared to a document that has been marked up with rich accessibility information.

On OS X, how will these components interact with the accessibility features?
