If your browser is online on an unrestricted network, then the tree heads will be kept up to date, and this will leak nothing. If you had your laptop closer for a weekend, open it up immediately and visit a website before your browser had a chance to update, well, you leak for maybe a minute or two you had your laptop closed for a weekend. So it's not that much. But we'll want to see how we can reduce this as much as possible.
