how to track transaction confirmations when you're "offline"?

when you switch networks or when you go offline the transaction is no longer being tracked for whether or not they are in a block so they will appear unapproved even if they are confirmed until the next block comes in.

No files, tests, or entry points are named. Start by reproducing the transaction-tracking behavior while switching networks or going offline, then inspect the extension's confirmation-tracking flow. Done means transactions that enter a block while offline are shown as approved when connectivity returns.
