Long timeouts on iOS if have WLAN connection but no internet

Trying to join another world on wifi when no Internet connection present.

What I expected to happen was...:
For the app to startup normally on the host ipad and open a world normally.

What actually happened was...:
Long delays at app startup and when opening world.

Steps to Reproduce:
1. Connect device to wireless network but disconnect Internet connection from router
2. Start app
3. Observe delay

I wonder if it is trying to check in somehow with a Mojang server because it sees wifi and assumes Internet must be present. Then eventually the request times out and load/open proceeds.
