I don't think multiple things are focused at once. Rather, certain
composite controls have a notion of which cell is "active", that becomes
the focused cell when you focus it. If you have a <select multiple> control
on your page, you can tell which items are selected even when it isn't
focused, and I think this is the same thing.

I don't see how that would translate into an accessibility API, even in a
native app. I think the author would have to semantically convey that via
some other means.
