"Exit offline mode" broken when snapshot was loaded from a live connection

[kenzieschmoll]

When connected to a live app, if you load an offline snapshot and then click “Exit Offline Mode”, the state of the previous connected app is not restored. This might be an issue with routing.

Now that we have integration testing, we can test cover this fix with an integration test so this functionality does not regress.

related: #5047. This may actually be the same issue. 5047 might have been reproduced with a flutter app and this issue was from a dart CLI app connection.

Closing as a duplicate of #5047, which tracks restoring the previous screen state when exiting offline mode.

If there is more work to do here, please let us know by filing a new issue with up to date information. Thanks!
