Verified on iPhone 6+ iOS 10.2.1, iPad iOS 10.2.1 build 60.0.3080.0 Canary

Verified the issue on the build 59.0.3071.27 beta tested on iPhone7+.
App doesn't crashes with the above steps works fine.

App is not crashing but also the expected behavior from original bug report is not achieved. The page is not reloaded when connecting back to internet.

Steps:

1. Turn OFF wifi.
2. Tap Menu --> New Tab
3. Navigate to any webpage
4. Error page displayed.
5. Turn ON wifi

App is not crashing, but also Tab is not auto reloaded.

It is working in a slightly different case:

Steps:

1. Tap Menu --> New Tab
2. Turn OFF wifi.
3. Navigate to any webpage
4. Error page displayed.
5. Turn ON wifi

Tab is auto reloaded fine and webpage loaded.

gambard@ Please let me know if this needs to be filed as a new bug?

Tested on iPhone7, iOS10.3 M59.0.3071.27
Link to video showing both the cases: https://drive.google.com/file/d/0B-xmXLQhjeKucjFHbWdlT3BnTWM/view

Actually I don't know how auto-reload is supposed to work. We are currently investigating what is the expected behavior and if it should be presented to the user or not.
No need to fill a bug, thanks for the testing!

Thanks for the update.
