Apple review process: Penalty for updating an app before it has been reviewed

I have submitted an app to the app store about a week ago. As far as I can tell, it wasn't reviewed yet.

Today my team discovered a bug in the app we've sent. It's not critical, but I would be very happy to have it in the store without it.

If I submit a fixed app before my app has been previewed, will my app be moved to the back of the review queue?

I found no direct reference to this question in the app store review process manual.
