Ensure that client "Review X changes" is updated periodically

We should make sure the "Review X changes" list is never more than 10 seconds old

Should we re-check upon A) approaching (if using a pointer device), B) interacting with the "Review X changes" list?

The X in "Review x changes" is currently updated by the GET call to /xb/api/v0/auto-saves/pending

We already call that every time...

1. The user makes a change
2. Every 10 seconds on a poll
3. Every time the "Review x changes" button is clicked and the list popover is opened

While the list is open, the poll is suspended but if a user attempts to publish and they are out-of-sync with the server, the response to that will update the X again.

Is there some scenario where this is not adequately keeping that number up to date that I'm missing?

yep #3 sounds good
