* @param roomId room id to find room and check
* @param predicate defines condition that is used to check the room state
*
* FIXME this does not do what it is supposed to do, and I think it is unfixable.
* `page.exposeFunction` adds a function which returns a Promise. `window[predicateId](room)` therefore
* always returns a truthy value (a Promise). But even if you fix that: as far as I can tell, the Room is
* just passed to the callback function as a JSON blob: you cannot actually call any methods on it, so the
* callback is useless.
*
* @deprecated This function is broken.
